I hate to admit it but what you say makes sense. In order for it to
idle with less advance it has to have a richer mixture and of course
a richer mixture works better when it's cold but I don't see how a
leaner mixture with more advance will produce more unburned HC's?
When the engine is running at the fastest speed it will run with the
mixture and advance as lean and advanced as it can be you should be
running very close to stoich? I say this because engine speed is a
result of gasses and heat produced, more means more so you are
getting all you can get out of the mixture at that setting IMHO?

OK- playing digest catch-up here again. For Salty Winters Rust Control,
I spray WD-40 on the undersides of all my vehicles. You can buy it by
the gallon at places like Home Depot, etc. My vehicles get a liberal
and thorough dowsing of the stuff (except on the exhaust and brakes, of
course) every 3,000 miles at oil-change time. SWMBO accusses me of
trying to get a high from the smell of it but actually the WD-40 works
well for me here in PA for Rust
Control.
Sorry I couldn't include the original post here but I haven't figured
out how to clip out a quote yet. Jack P.

This has been a lot of fun but really I've found the rubber hose
solves it most of the time since it does act as an insulator to some
extent so the outside stays hot but the inside is cooled by the
incoming fuel. Don't use clothes pins, I really don't believe they
do anything unless you use an awfull lot of them. Before we had
reliable rubber hose for fuel applications the old timers did what
they could to insulate the lines but now we have no excuse :-)

Again you could have a combination of percolation and vapor lock and
they could be caused by the same problem, too much heat getting to
the carb or it's base and affecting the temp right at the inlet. It
may not even be a line problem but still be vapor lock in that case.
I believe that was the problem with my van with cast iron EGR plate
under the carb along with the exhaust path under there as well. By
looping the rubber fuel line up about a foot over the carb and back
down again to the inlet I ensured there would be liquid at the inlet
and the problem went away. Even if it boiled, the weight of the fuel
kept some liquid at the bottom so the float bowls always had liquid
fuel rather than fumes.

When I finally get to my bronco 460 project it will have some

stainless braided line for everything including fuel. I don't
anticipate any more fuel related problems when I do that along with a
rubber base spacer of some sort.

I notched my first one too and also reinforced it but the rear exit
manifold is really much more elegant and easy to work with and stock
truck exhaust systems were made to fit it perfectly so there are
several advantages to having the right manifold. I found that no
matter how I routed mine it was somewhat restricted due the the
location so you probably could get better flow with the truck
manifold as well.

Of course the headers didn't require notching and the Stan's tri-Y
sound like the best way to go since they don't get too close to the
starter. I may try them on my bronco project.

I guess if I had it to do all over again I'd get the L&L mounts and
headers that fit. In the long run you save money by eliminating all
the trial and error and wasted exhaust parts etc.. I bought and
modified two systems before going to headers and custom exhaust. I
could have done this off the bat and saved myself some work and money
as well.

Hi Dave,

I think that David hit the nail on the head in pointing to the ground.

Ahh! but it is grounded through every bulb filament.

>and then turning the panel light dimmer all the way down, and lo and
>behold, the tach comes back to life w/ the panel lights completely dimmed

This verifies that the ground is the problem. Like David said, if you are
100% sure that the external ground is good then it may be inside the tach.
Good Luck!

deac,

Check out http://www.ford-trucks.com//lc/lc.php?action=do&link=http://www.windsor-fox.com/ for an EFI harness. Probably a higher
$$ approach but they will custom build a harness that will plug directly
into your existing wiring.
