Caterpillar V60B:
F227 continental low compression

I have a 1974 cat v60b with a continental f227 6 cylinder flathead propane engine. Purchased it non running. Previous owner replaced starter, distributer, plugs, wires, rebuilt carb.

Engine will not start. Compression test on cold engine reveals 60, 60, 60,60, 95,100 when dry. Added a couple squirts of oil and they are as follows:
1=75 and holds. 2=50 on first stroke, then 80 then drops. 3=90 then drops. 4=90 then 110 then drops, 5=90 first stroke, then 145 then slowly drops. 6=90, then 100 then drops.

Sounds like bad rings to me. Anything else to look at? I was hoping a head gasket, but that doesn't look likely.

Hello, I would suspect a head gasket, If you take the head off check for cracks and warp. We use to double up on the head gaskets for really bad ones.. My 2 cents.

I would try to get it started and see if it smokes. If the distributor was replaced is installed correctly and the timing correct? It should start even with 90psi compression.
