quote SteveAbe:

yes i am running in a barrel .I pulled one plug wire at a time while running made very little difference on either cyl. It wont start when the lower wire is unhooked it will start when it is hooked and the top one is unplugged. I have that wrong it is the other way around i put a new pump in it thats why i tried to run it in a barrel It has always had 16/1 gas my grandpa bought it new. I always drain the carb when done it only gets used once are twice a year so i always drain it. With it being my grandpas im kinda anal about this motor i have 4 or5 other motors so im used to these older motors.Thanks for the tips i think i will pull the head and see whats up

OK, drain the gear lube and rotate the flywheel with the plugs out like Frank suggested. Try NEW spark plugs and a different compression gage.
Do a spark test also. Sounds like you drained the carb pretty well, so that should not be an issue. Running the engine in a barrel, not under load, makes it tough to evaluate it easily.

Can you do a video of the engine running and post it? Maybe someone here will pick up on something. Remember, do the easy/basic stuff first. Try to avoid pulling the head until you have verified the compression readings with a different gage, hopefully you will find a simple solution.
We realize this engine has a special place in your life, I’m sure you will get her purring again.
