The early 160's, are those the lighter flywheels that give you a little more timing -vs- the 200 flywheel ?
Also I got my motor going with the 390 set up, I went with a 100 main and it seems to be fine on the big end. Only problem I am having is it has a choppy idle, and dies when I let the rpm get to low. To rich, to lean, maybe not running the fuel pump is the cause ?

Yeah some had a thinner flywheel. That's what they called it, and they had 3 more degrees built in it. Honda changed them for safety reasons, but they seem to work well for the QMA guys. Then QMA made them illegal because of the advantage in the super stock class.
Maybe you don't have the air fuel mixture screw setup properly. That will normall keep just enough air in the carb to make it idle, and not cut off. Other than that you will have to keep the butterfly cracked with a high idle.

The little brass nipple on the butterfly side, it has a little screw that turns about a half, is this the air fuel mixture screw ?
Thanks for the flywheel info. I pulled one off an old 160 I had along with the 14cc head and flattop piston. I'm curious with the flattop and 14cc head and the 200 head gasket, how much compression should I see when all bolted up ?
