49 Chevy panel truck model 3100 with a rebuilt 216 engine. Attempting to set the engine up, but it seems to be running to rich. There is little or not smoke but the exhaust is so rich that you can't stay
in the garage with the door open, my eyes burn and the exhaust makes it hard to breath. How do I lean it out so that it's not so rich and to get the engine to idle smooth. Thanks for the help.

Regards,

Dave
