High and low settings for stock? I think I was 1&1/4 to 1&1/2 out from seated but can’t remember.
Thanks

Re: WRA-31 settings for 75 jdx8
Book says idle screw 1 1/8th turn open. Hi speed 1 1/8th open for 75.
On the idle: if it dies it is probably too lean. If it fouls plugs on start up, or the rpm hunts once the engine is warm, it is too rich.
The recommendation on the high speed is max performance, then open 1/8th turn. Better coked than smoked!

Runs great! But in the years since I started this project I seem to have misplaced the spacer block between the carburetor and the silencer. Anybody have one?
