« on: November 08, 2018, 12:42:08 PM »
engine will start up first kick . right hand cylinder will run ok on its own with carb air screw 1 and 3/4 turns out but left cylinder needs to be nearly 3 turns out before it will run on its own . will rev ok but on the road no power and misses on left side .new points , plugs , condensers, different coils, different carbs ( all been cleaned)

Could be anything. Are your baffles and exhausts clean? Are the points set correctly using a dti? Has it ever run right or is it a new purchase?
