missing on couple cylinders


Recommended Posts

With 110 psi compression on the two suspect cylinders it’s unlikely that a head gasket is the culprit. You’re either not getting the spark properly or there’s a total blockage in the intake manifold feeding the front 2 cylinders. I’d first double check the plug wires to be sure they’re not crossed/reversed.

We check the comp and we got only 75 pounds the valves must be sticking 

 

I am a bit confused. In your first posting you said the compression was 110. If you have a valve sticking you would have zero compression in that cylinder.

I would check to see if the spark plug wires are arcing / shorting on something or even on eachother. Start it in the dark and take a peek, if they are arcing your see it plain as day.

I had a similar problem on a 1938 Buick. It turned out to be a bad intake manifold gasket. It was pulling plain air in rather than the fuel air mixture. When I would spray starter fluid near the leaking gasket it would pick those cylinders up. Just watch out for the fan and for safety’s sake, I did it when I first started the engine before the exhaust manifold got hot. Good luck! Some problems can be a real bear to figure out.

we had good  spark at the plugs I crossed them with a screwdriver I'm thinking that the rings are stuck from sitting for so long the old guy is trying to get it running so he can sell it 

 

it is a 1950 1/2 short box with a fluid drive  he can not shift one of the linkage on the transmission

How about a crack in the distributor cap or crack in rotor.
