I can't get my 503 to start, good spark, seems to be pumping fuel, but none is getting to the spark plug. I just pulled the motor, 160 lbs compression, now to check the crankcase seals, I made to covers for carb and exhaust. Now I need to fab the hose/fittings to pump up the pressure, a couple fittings and I'll be on the way.

Well, I think I found the problem. I pulled the motor and checked for crankcase integrity, air blowing out the flywheel side so loud you could hear it with everything buttoned up. After pulling the flywheel, I could feel the air coming out on my cheek next to the shaft, only 3 lbs needed. New seals are definitely in my future.
