Wont Stay Running, What’s The Issue

It could also be a clogged idle circuit ?

 

Yes, it would’ve kept running but it dies eventually either way. So i guess option 2! I’ll check the float height again, but when I took the top off of the carb the bowl was pretty full. How do you recommend I check the pump pressure? I’ve taken the carb inlet line off and cranked it and it shot fuel pretty good.

 

The FSM explains it precisely. Both pressure and volume. For a Carter Yf, the static pressure should be about 2.5 or 3 psi.

But first off, "pretty full" means nothing to a carb. The float height must be set very precisely, and according to which float valve is used.

My '56 F-head was having a problem that turned out to be the soft tip of the valve needle getting sticky, due to age and/or ethanol. It wouldn't open until the float dropped way down.

 

It won’t run. Giving it any throttle will kill it. I can try with my foot to the floor next time, I’ve been nervous about that lol

 

I know it sounds strange, but I've had bad ignition points and/or poor timing cause that. Might be worth checking, and is the first step in any tune-up by the book.

 

That was my first thought too, confirmed after watching the video.

 

I replaced the condenser a while back, it came with a distributor rebuild kit.

 

Gotcha I’ll double check all of that and let you know what happens!

 

9/10 new condensers seem to be faulty for whatever reason. do you have the old one to try?

 

If it is a bad condenser it will cause the points to burn, so they will need tuning up regardless

this is a pretty cool project, obviously geared towards chevy stovebolt sixes, but i'd be willing to bet it'd be pretty close to right for a jeep too.

 

Go to NAPA. Get the Echlin/Blue Streak made in Mexico.

 

I check the capacitance of condensers when installing new or having a mystery problem. Most meters have a function to check that size. If needed, I can scrounge up how to check with an ohmeter

 

I don't get scientific enough to check "the capacitance of condensers", a good one is a good one, and the Blue Streak brand of points and condensers are good ones.

That is all I will use, and never had any problem with them. The imported crap some suppliers sell are not worth taking out of the box.
