I have a 38WC. The IT manual sez there is a timing mark on the flywheel that is 30 degrees BTC and marked F for fire. I have peered into every hole I can that looks at or even near the flywheel & have not yet seen ANY marks! There is a golf ball sized opening on each side just below the frame rails that looks directly at the outer rim of the flywheel. I have scraped all the way around the flywheel twice one window at a time. No marks. I started it, stuck a wire brush in the hole, doused it with solvent, wiped it all off with a shop rag, shut it off, marked it with a soap stone & went all the way around. No marks. There is a hole between the block & clutch housing on the right side below & to rear of the right headlamp. Didn't see any marks there either. Removed the belly plate covering the throwout bearing etc. Removed the standard issue bumble bee nest but no timing marks. Even looked for marks on the shaft through the hole between the mag & the governor housing. Nothing.Gave up & bent a wire to feel the piston through the spark plug hole using a dial indicator. Rocked the crank back & forth 'till I measured .015" both BTC and ATC. Split the difference, set the crank at this middle position then looked in every hole I found. No timing marks. I then set the mag to trip impulse at this position then backed the engine up, rolled it in running direction 'till the mag just stopped. This should be the 30 degree BTC point since it has a 30 degree impulse coupling on the mag. Looked in all the holes. No timing marks. I put the mag on as described above, completely disassembled, cleaned & re-installed the carburetor and now it starts on the third impusle, doesn't kick, and idles well. I am simply stumped by this WC's timing marks! Am I looking for the right thing in all the wrong places? Thought you guys might be able to help. Sorry it's been such a long story but I thought you'd get a kick out of a JD monkey gettin lost on an Allis. Still been fun and I like 'em all! Thanks for your time and advice. Later.
