Timing issues, again

[Anonymous]

Well, I got the motor in and everything bolted up (finally after nearly one year). Now I am having problems cranking the engine.

I think I have isolated the problem. Timing.

Awhile back this forum had a VERY length discussion on timing (mostly about CC's timing issues). I tried several searches and didn't find anything.

Anyone have any of these discussions bookmarked or saved?

What's the problem...maybe we can help?

Thanks Slade.

I can crank the engine. Sometimes even get it to spit and sputter a bit before it dies. But I can never keep it running.

Right now this is my setup:

-Rebuild 200 from local shop.
-Factory blueprinted with 020 over bore
to clean up cylinders.
-Motorcraft 2150 with Clifford adaptor (the one you sold to me last spring)
-Duraspark II conversion with proper coil
-New wiring
-New starter
-New starter solenoid
-Stock everthing else except dual exhaust muffler (single in, two out)

The engine is set at 6* BTDC. The only thing I adjust, as far as timing goes, is the distributor. I advance it or retard it.

The carburetors mixer strews are turned approx. 1 1/2 turns out. I am getting the proper amount of fuel and pressure (bought regulator and have new line installed).

Any ideas why it might be stalling?

One more thing. If I change over to the points system, it will idle smoother but while eventually stall.

I had the same symptoms and found that i had adjusted the valves adjusted incorectly. some were not closing all of the way so it acted like the timing was off.- just an idea.

I had my distributor in wrong...but my brother(the smart one) just changed the plug wires around and fixed it. Same symptoms.

stang;
You said the timing is at 6 degrees BTDC: how did you set it?

Do you get a fuel smell, like richness? Or, could it be a vacuum leak under that carb? To try out a vacuum leak scenario, try backing the air screws of the carb out to about 2 or 2-1/2 turns (from the current 1-1/2 turns) to see if it helps. If this helps, there might be a vacuum leak under there somewhere.

When I had this problem, it was because I'd failed to reconnect the "runtime" wire from ignition to coil. The bypass was on there and working, but not the resistive one.

Okay, here is where I'm at now.

I checked over everything yesterday, timing (with light), wiring, fuel line, fuel pump, distributor, vacuum lines (with guage) and I believe everything else not listed.

I was able to get the engine to idle much better this morning (strange considering how cold the weather has been). The thing that made the difference seemed to be the two fuel/air mixture screws at the base of the carburetor. But I'm just about out of thread adjustment. I may have about 1 or 2 more turns left before the needle fall off.

Tomorrow I am going to try the YF with my rebuild engine. See if I can't get it to idle smoothly with it installed. If so, then I think I'll be looking for a new carburetor.

Stang200,

Hey, I was also having problems with getting my motor to run. One person suggested that I had too much fuel pressure going into the carb. I bought a fuel regulator and a pressure gauge. No matter how I set the regulator, it would only put out .5 PSI of fuel. Not enough fuel to keep the motor running. Check that out.
Was your cam taken out of the motor during the rebuild? Is it possible that your cam is off by a degree or two?

Ted, I think it is more of a fuel issue now. I was able to get the car running very smoothly yesterday but very briefly.

During the rebuild the cam was not removed. I originally planned on replacing it but opted against it. Lack of funds. Other than what I have posted so far, fuel delivary seems to be the issue.

It's getting cold again in St. Louis so I'll have to wait awhile before I can work on the car (no garage). If anyone has any more ideas, I would appreciate it.

Thanks.
