Re: 1940 Custom Low Compression

When did valve job all rings and walls looked fine, not even much of a ridge at top. Did only one valve at a time so could not get mixed up. Did all compression checks hot and cold. All plugs out, carburetor full open. Actually the cold reading the same amount of compression. Should there be a difference between hot and cold? Maybe try a third compression gauge.
I will check, but after twenty years and thirteen thousand miles the oil canister must be correct. The bottom of the canister gets fed from where the oil sender gets its pressure and the top of the canister dumps a little higher up the side of the block.
Perhaps will try running without new filter, and take off both oil canister lines, to make sure nothing got clogged.
