I need help!
I'm having problems getting a newly rebuilt 292 started. Fuel and spark delivery are OK. It has to be timing related. I'm pretty sure the firing order is 15486372.(?) We put number 1 (front on passenger side?) at TDC, aligned the middle line on the crank pulley with the timing pointer, and pointed the rotor at the number 1 plug wire.
Nothing but a few backfires.
What am I doing wrong?

Any thoughts would be greatly appreciated!

 

check your point gap.... should be around......018 or .019

firing order is correct.....just double check the order on the cap!!!

 

Are you sure you don't have it 180 degrees out? Make sure that the #1 cylinder is on the compression stroke. When you bring it up to TDC put you thumb over the spark plug hole and make sure it's blowing out around your thumb.

 

Are you sure that you have the number one cylinder at TDC of the compression stroke?

Make sure you have a good ground between the engine, chassis, and battery (three points).

With a points distributor you can static time the engine.

You can use Ether to help get the engine started.

 

I ran into this same problem when I rebuilt my 272 for my '56. What I did wrong had to do with the timing chain. I aligned the dots up on the crank and cam timing gears, like a windsor series, instead of counting the number of pins on the chain. I had the chain on backwards so I did not see the two identifying marks on the chain. My Ford manual says there needs to be 12 pins between the two dots. I was fortunate in that the pistons didn't interfere with the valves.

Hopefully this helps!

 

After getting some good ideas...I have a stupid question.
Which way does the crank rotate when viewed from pulley end?
This is a marine engine...It just hit me that it may be opposite rotation.
???

 

 

Reverse rotation engines run counter clockwise. Reverse rotation interceptor marine engines use a set of timing gears instead of a timing chain. Try this website.It has a manual for a 272 interceptor. http://personal.nbnet.nb.ca/khan/jetsite/intrcept.htm

 

I too have a similiar problem.I installed new everything on my 272/292 yblock 2 barrel.When I cranked it over it backfired some and then starter would jump out.--now I have to put distributor in but not sure of if I'm in the right gear tooth.--so now do I have to find tdc and put plugs back in and cap on and --oh yea--if firing order is 15486372--but where do you start on the cap for no.1? thanks--

 

Your cap should be marked with the number "1" if you look closely. As you engage the distributor gear on insertion, you will see the rotor move, so you need to offset a bit prior to insertion to get it to end up pointing at number one. Dont do the dist until you have determined the number one cylinder is close to TDC compression stroke. TDC should occur when your timing mark and pointer are at zero. I think the old posts above cover TDC.

The crankshaft rotates clockwise. Distributor counterclockwise. If priming oil pump with tool and drill before distributor installation, be sure to set drill for counterclockwise action.

 

If the above suggestions don't work,

You may have to remove the timing cover and ENSURE that the timing marks are correct!
(alternatively you can ask the person who assembled it how he/she assembled the timing set........ask them to TELL you how they did it don't ask IF they did the 3 o'clock method)

The timing marks on the crank and cam sprocket MUST be at "3 o'clock" not opposing each other at 6 and 12 o'clock respectively (some mechanics confuse the Y-block with "other" engines).

THANKS everybody--I am almost ready to start again-but the winter weather just hit today and I am putting everything in for winter--sucks---and then back in the barn for distributor 1o1.thanks

 

i bet its 180 out or wrong tooth at the distributor

 

F700-I am starting to believe this is true.I have done everything else--I need a mechanic--ha ha!!!I guess I will try it 1 more time.thanks

 

good luck take your time when you do it
