hello my idle speed is bad when put in gear it drops to 600-500rpm and the engine twitching vibrates and finally dies. but when not in gear the revs are 900 1000rpm. the engine revs fine when I give it a little gas on the throttle al the way to wot.

is there an adjustment screw i can turn up the revs a little to have a good idle speed around 700 800 when in gear?

the carburetors are in sync I have test it with carbpro sync it's only the idle .
