Oh I may have discovered a big problem here. I checked the oil dipstick and it was higher than the high fill line. Several months ago I noticed the same thing and drained the oil. The oil seemed very thin at the time. I put new oil and made sure I was right in between the lines on the dipstick...

Here is todays update. Got in the truck early this morning and she started right up. This is different than before where it would take weeks of sitting there or me pulling the plugs to air the cylinders out. Very rough idle. Didn't need any choke to start. Idle sounds more like a Harley than...

Ok here is the labor day update. Pulled the top of the carb and adjusted the float level. Cleaned out the bowl and cleaned out the jets (no contamination anywhere). Turned the engine over with a camera recording the carb and once the bowl filled up the gas stopped flowing. Seems like that is...

Are there any good guides to checking and adjusting the float level?

Here is the latest. Brand new coil, new old stock not the chrome imports, new cap and new rotor. Got it all installed, and she started right up. Instantly. Note that the truck has sat for about 5 days without turning over. Ran exactly like before, few minutes no problems. A little grumbly but...

It's not a stuck float. Checked it this morning. Either something is fouling the plugs (not fuel) or the coil just doesnt have the umph (maybe thats fouling the plugs?) We will know soon enough, coil should be here in a few days.

I will certainly check that tomorrow morning.

One more update and more confusion. I had pulled all of the plugs early yesterday (around 11am). The plugs sat out overnight as did the engine. No plugs installed. This morning just in preparation for the new coil coming in, I put all of the plugs back in. I was 100% sure she would start and...

I have the electronic ignition on this truck. Petronix MV-161A

Here is the update. I checked the coil and all of the measurements were fine. Pulled all of the plugs and they were wet BUT that might have been from me checking compression (and adding oil as part of the checking process). I decided to order new plugs. Got the new plugs this morning...

I ordered a set of new plugs. Who knows how old these are and they are pretty beat. I don't think its the plugs but at this point ill try anything.

When you say "lifter cover" what exactly is that? I have not heard that term before. Looking down on the engine all I see is the head (where the spark plugs screw in). Could you clarify?

Hello all. I have a bizarre M37 problem that I can not figure out. I'm hoping you smart folks might be able to point me in the right direction. Firstly this is a 1952 M37. Mostly original but it was converted to a fire brush truck. I have done extensive repairs to this truck. New wiring...

Now that I looked closer at the pictures i see brass shavings. It looks like my rotor is hitting the electrodes and shaving off brass filings. The path would make me think the tracks are after the electrode. Why would my rotor be hitting the electrodes? I thought they weren't even supposed to...

I have a 1952 M37. This is a brand new distributor cap, rotor and Pertronix electronic ignition. I have been having some bad issues with getting her started so thinking I'm having an ignition problem I pulled the cap and noticed carbon tracks in the cap. Seems pretty bad considering there might...

Are there any steering wheels that fit the M37 that aren't the original? Some other military truck maybe?

I would like to replace my steering wheel with one that is a bit smaller. I am also installing power steering. Does anyone know if the original Humvee (HMMWV M998) wheel will fit? It looks good and is 14" rather than the monster 18" I currently have...

I have an M37 that I believe had a heater at some point as I did have the defrost cowl (which is for sale if someone wants it). The question is that I have a hose that goes from the front of the block to the rear. I am guessing that this was the feed to and from the heater and it was bypassed...

I took the carb apart (for what seems like the 20th time) and put the old piston in. It seems to have helped some but the problem is certainly still there. New gaskets too. If I slowly press the accelerator down its great but if I push it down quickly its just pops and sputters and will slowly...

I checked the vacuum and i have 17" which seems exactly correct. What I noticed today is when i slowly accelerate its pretty good but when i push fast on the gas it craps out. I did clean all of the filters, tank, firewall and inline. I did also blow out the lines. I am confident its no longer...
