Thank you all for the help. I believe I have solved the problem. After gravity feeding the carb and it not fixing the problem I decided to buy a Solex like carburetor. After installing the new carb it's running great. It idles great and the exhaust pops very little now.

I adjusted the intake and exhaust valve lash. They were ALL over the place. I found intake lash ranging from 0.010-0.020" and exhaust lash ranging from 0.0090-0.018". I set them to: Intake: 0.018" Exhaust: 0.016" I also checked the carb bowl and float needle for debris and found nothing. It...

I also wanted to ask about the mechanical timing advance weights in the distributor. When using the timing light it seems like the timing advance weights are coming out and advancing the timing at anything above cranking rpm. I have 12 degrees when cranking and 22 at any rpm running, even around...

Cleaning and gapping the spark plugs was one of the first things that I did. I just cleaned and checked them again and they are all at .030" I also just did another cold compression test to compare the numbers to hot. All of the spark plugs definitely look used but I don't see any...

I adjusted the timing as was suggested by rotating it to each extreme. I set it to the smoothest running/highest vacuum at 12 degrees when cranking and 22 degrees when running. I also adjusted the mixture screw to the smoothest running/highest vacuum. It didn't seem to make much of a difference...

There are no marks or holes in the crank pulley like I thought there should be. I found TDC on the compression stroke and marked the pulley and then used a timing light to time it. The timing light should be giving me an accurate reading. I will try advancing the timing and see how it responds...

I guess I'll have to take the oil pump out and move it over a tooth or two. Then I'll re-time it.

I ran the jeep last night, took some videos, and checked for spark. I checked spark by grounding the #1 spark plug on the exhaust manifold and it had good spark before and after running. I have attached a picture of the engine bay to show how the distributor/ignitor is positioned. When I set the...

Thanks for the reply. No black smoke but it does seem to have a small mis at idle. I took my vacuum reading from the intake manifold fitting right below the carb. That should give the same effect as plugging it, right? I have checked the carb gasket for leaks with an un-lit propane torch and...

Hello, I have an M38A1 that my grandfather restored about 20 years ago. It has been stored in a garage for about the last 10-12 years. I'm trying to get it back up and running but have been having some problems with it after it warms up. The jeep will start and idle fine until it starts to warm...

Good news. It's alive!!! https://youtube.com/shorts/otMfJGTqus4?feature=share First time we got the truck up to speed and let the clutch out it fired right up. Guess the shock and higher rpm did make a big difference. The truck has no brakes (fluid leak somewhere) and, of course, it busted...

Wow, this has gotten way more guys interested in the results than I thought it would! Going to finally have some good and warm weather tomorrow to try to tow-start it. The only question is, the truck that I will be towing (and trying to start) is equipped with the air assist steering. Will...

Hey all, I stopped receiving emails for replies for this thread so I assumed no one else had replied. Guess I was wrong... Haven't done the compression test yet because life had other plans. Going to stop by the hydraulic fittings shop tomorrow and get an adapter for my compression tester to a...

Already removed the air filter and tubing all of the way to the turbo. Had to remove it early on to replace the starter solenoid. I just have a helper use a board to simulate the air restriction of the filter.

No success yet. I did try soaking the cylinders with a 50/50 mix of ATF and Marvel Mystery Oil for a few days, adding a few ounces every other day. I'm not confident that the mixture did much of anything, because I also soaked an old carbon covered spark plug in the same mixture and it didn't...
