The purpose as it was explained to me was to simply help the engine warm up faster.  The retard vacuum line can be removed and plugged with no harmful side effects other than more polution as the engine warms up.  But if it was not working to begin with it should help.

Kourtney,
The dual vacuum diaphram is an advance/retard mechanism.

I'm not sure of the advantage of this.

Subject: Plugs and hard starts.


Well with this cold snap came some rough starts for the truck.  It would fire
initially, but if I didn't keep it running it was all over, would flood itself
out and be impossible to start without a jump, a combo of too rich on the choke
and a 5 year old battery that's seen better days.

I finally got the choke leaned out quite a bit and checked all the timing/points
that you would normally check, everything was dead on, then I realized I hadn't
touched the plugs in a while, though its only got 10K on it since the rebuild.
What I found amazed me ... the plugs were nearly perfect, a little dark in
color (probably from the really rich cold starts) but were nearly perfect, there
was no pitting, no rounding, nothing, but the gap was too narrow!  They were
all (except for one) at .030" but I know I set everything at .035" before I
put it in.  What would cause these to get narrower ?  Would 2 gauges vary that
much ?

Also had 2 plug wires that were messed up, one just wasn't plugged on all the
way (#2), and another fell apart when I touched it (#1).  I had a spare wire
laying around from the old motor that I replaced the bad one with, and now it
runs like a dream, unbelieveable how great it ran after that (perfectly smooth,
sounded like an old musclecar again :)

My next question is DuraSpark related, I've got the stuff to go to it, and will
be making the move sometime soon (only been saying that for a year, but this
has motivated me to get a little more spark in there) ... in the meantime can
I run the larger cap/rotor combo with the 5.0 plug wires ?  I hate the fit of
the replacement wires these days and the 90° boots/fittings on the later
model caps is really nice, but I'm afraid the cap may rely on the higher energy
of the ds system to fire it ... anyone know if this is really the case or not
?

You can go to the larger cap at any time.  It should be an improvement on its own.  You will find there is less cross fire since the contacts are spaced farther apart.

Having hardened valve seats (area of cylinder head the valves set into when closed) installed requires removing your heads and bringing them to a good machine shop.  Leaded gasoline prevented the valve seats from eroding on older engines but the switch to Unleaded gasoline required the use of hardened valve seats that "unleaded only" vehicles came from the factory with.  There are also some lead substitute additives available but I do not know how well they work.

Higher octane gas is only necessary if you have problems with your engine detonating or "knocking".  Typically when accelerating or the truck is under load.  One reason your engine may knock would be if it is an older high performance engine that came with a high compression ratio.  The lead in gasoline also was an octane booster and allowed higher compression and more advanced timing.  If your truck doesnt knock then higher grade gas can be a waste of money.

A popular brand of premade steel beds is Hilsboro.  They manufacture stock
trailers.  They are kinda pricey (around $1000, I believe).  Sure look good
though.  Might check with local places that sell trailers, especially stock
trailers.  Also check with a local welding/fabrication shop.  A friend had a
custom flatbed made by a local welder, very nice.  Had hidden 5th wheel
ball, integrated rear bumper, lights, headache rack and tool boxes mounted
under bed between cab and rear wheels.  I believe it ran him about $900 when
it was all done.

Just a thought.

-I don't know anything about the local laws, never heard of anything like
that in South Dakota or Nebraska, seems like every third pickup has a
flatbed here...

Wish, I ran the large cap conversion long before I installed my Duraspark
with no problems at all. Even had a stock coil on it. When I buy plug wires
for my 390, I get a set for a mid 80's 460. They have a little extra length,

Here is one that has me stumped.

My 79 302 will periodically (once every two days or so) just cut out while
driving along. I then put it in neutral pump the gas, start it and away it
goes.

The other day, it did so, and wouldn't run until I had made several start
ups. There is a new gas tank and fuel pump, cap and rotor.
Today, it did it again but started right up and no problem. The
truck had been runfor an hour today with no problem. It feels like water in
the gas but unlike that problem, it starts up again right away and runs fine
until the next time. I put a bottle of gas line anti freeze just to be sure.
I have had this happen with wet ignition but when that happens the truck
won't run again or at least pull itself without drying the ignition out. Not
the case here.

The truck sat for 7 years until this spring when I bought it and
restored it. Does this sound like a carb problem to anyone?

Greetings. This is my first post though I've been subscribed to
the list for over a month. I had a similar problem with my 67
F100 (300 6cyl, 3 speed), so I thought I'd speak up. My problem
occured after I installed a new fuel pump. A neighbor speculated
that the new fuel pump was creating too much pressure for the
carb (single bbl stock) and suggested that I install a relief
fuel line (with an adjustable valve) from between the fuel pump
and carb back to between the fuel tank and fuel pump. That's been
about four or five years ago and it solved the problem for me.
(The fix required two "tees", one of those inexpensive little
valves, about three feet of fuel line, and about 15 minutes of
time.)

HTH,
Bill

I had a similiar problem with my '76 with a 302, after a lot of messing
around like changing all the hoses from the gas tank, changing the fuel
pump, the ign module, adding all kinds of  additives, I finally took the
top off of the card and lo and behould the gasket had dropped down and
was holding the float up and in this condition the truck ran fine until
the gas in the fuel bowl ran out it would quit. I performed a radical
cutting (trimed) the gasket so the float would be able allow the gas to
flow. Good luck.

Thanks for the info.  I have an idea on how to get rid of the rust.  The
rust isn't reallly bad yet.  It isn't putting holes on the inside of the
bed yet, but on the outside right above the wheels.  I am also
eventually going to put in a paint in bedliner.  I am probably going to
go with Herculiner but there are others that I have seen around, which
is best do you think.

The registration fee is for your truck.  If you don't pay the
fee then you have to pay to get in the gate and won't be eligible
for the door prizes, which can be substantial (such as the $8,000

>I'm wondering if anyone
>knows of some plans to do a project like this or if anyone has done this
>themselves can you give me any hints or guidelines before I start.

I ran a flat bed for a few years on my 76 F-250 4x4.I live in Nevada and
traveled to Oregon,California and Utah with it and never had any problem
with scales,etc..
First thing is to measure from the top of the FRONT wheel to the top of
the fender.This is the distance you want the bed above the REAR wheels
for a
clean,well proportioned flat bed.Another appearance issue is width.
I measured my cab at it's widest point and added 2 inches.1" on each
side.
And a third apperance issue is rear over hang.I cut my frame off behind
the lasdst shackle to shorten the over hang,making my long bed about
7'6".
After determining the necessary measurement get a 4 by timber(My 4x
needed a 4 x 14).Cut the bottom to follow the contour of the frame.
I had some 3/16 flat stock bent as follows.
1 1/2"x 1 1/2 lip for the floor to set in.
3" top.(the piece the stakes would drop into)
5-6" side
2" lip on the bottom.
__________
l         l_____
l
l        Looks like this from the end
l_____

 For the rear I measured from the top of the bed to the bottom of the
frame.I then replaced the 5-6" measurement above with this
dimension.Then I went outside to outside of the frame rails,deducted it
from the width of the bed and and had the slope of the rear of the bed.
Sort of like this with the "0s" being tail lights.

This is a brief over view of building a bed. By the time I got done
with mine I could have bought a nice bed with what I spent on
metal,lights, wood ,nuts, bolts etc.Not to mention who knows how many
hours.
I WANTED a flat bed.I removed a perfectly good bed(which I now have
back on)
to install a flat bed.To build a NICE bed is not a simple or cheap
project,
but when done right they do look very nice.Now that my 76 is not a daily
driver I may just put my flat bed back on.I'm pumping the 428 up and
with the lighter weight of a flat bed the bow tie whippings could be
even more severe.....
Any more questions on bed buildin' let me know.

Great!  I'll probably pick that stuff up tonight then, waited til I heard from
you guys 'cause with my luck there would've been something else a little different
and I'd have been without a running truck.

As it turns out I'm with a truck that won't stop, when I did the disc brake
conversion apparently I didn't get the left caliper seated correctly, it popped
out a little ways and wedged itself ... burned off the entire pad and some of
the plate that holds the pad ... not to mention doing a bang up job of turning
the rotor down to well below spec ... so I've got a new rotor getting pressed
today and I'll get it all back together tonight I hope.  Any tips for being
sure the calipers are seated correctly and don't pop out ?

Sounds like a rusty gas tank. There is a sock on the end of the pick up tube
in the tank. Next time it cuts out, get out and shake the devil out of your
truck to slosh the gas and see if that helps. Or try sloshing it and see
id=f it goes longer before it cuts out again.

Another possibility is a split rubber fuel line that is sucking air or
losing pressure.

The setup I have seen and read about in books is a two vacuum lines in (one
ported and one from manifold) and one vacuum line out to the distributor
vacuum advance. This type of coolant temperature operated PVS (ported vacuum
switch) is switched into operation when the coolant temperature reaches
around 235 degrees. It is mounted into the thermostat housing on most
engines, but found mounted to the water pump of others like the 351
Clevelands including the 351M and 400.

The PVS switches the ported vacuum to the distributor advance over to
manifold vacuum when the engine temperature reaches around 235 degrees. This
will advance the timing and speed the engine up in order to help cool it
down. The vacuum supplied to the retard side of the dual diaphram is not
effected with this particular setup.

There are more details and other setups with a cold start spark advance
included with this. The cold start spark advance wasn't used until the late
seventies.

Hope this helps.

Thanks for the support John :)  That was literally my first time putting that
system together, so it probably wasn't seated quite right, I was going to go
back and check it since the pass. side went together like butter, but I figured
it was my first time before so it just seemed harder ... guess I should've checked
it... oh well, they have all the parts in stock so it should be running by this
evening, and stopping too of course :)

Guess that explains the low fluid in the reservoir too (since the piston was ....
