6 Cylinder funk questions.

Manual: Look for a manual that covers the industrial 226 engine.

Carb.: I would suggest a good cleaning and carb kit (for a late '40's or early '50's truck). Also check to make sure the carb is getting plenty of gas from the tank and that it is getting into the carb. Dirt in the tank can plug up the line.

Exhaust manifold: Try an auto or truck salvage yard for a used manifold off of a late '40's or early '50's 226. Also, try a hot rod shop that customizes old cars and trucks. They usually throw away the old engines and you can probably buy one cheap.

Good luck and have fun.

"Governor: The difference between your Funk and '49 is that the '49 attaches directly to the engine, so the oil pumped in by the line goes directly into the engine. The Funk governor is totally enclosed. There is a small pipe plug on the side of the Funk governor pulley housing. Fill the governor with engine oil through the top hole until oil comes out of the side hole, no more than that. The inlet at the top should have a spring loaded flipper that will let the air out as the oil expands when the engine warms up during use, preventing oil from leaking out of the governor seals."

Is this a fact? My '52 8N with dealer-installed Funk conversion has both an oil inlet and outlet (from galley to sending unit) line, and they don't look kluged; when I recently got the tractor, she was leaking A LITTLE oil out from the governor pulley hub, and as I went after this leak, it progressively got worse. I attributed the original leak to a badly-installed seal in the governor casting, but I've removed it now and can't find a replacement.
I guess I wouldn't mind modifying mine as you describe above, but I still need a new seal!

I went to NAPA today and ordered a rebuilt Carburetor. Hope that fixes my idle problem.
