[QUOTE="wmk0002, post: 484291, member: 13975"] Appreciate the reply as always Todd. Parts diagrams show the carbs to have identical jets. I'll still check them to make sure some goob didnt try to up the main jet size for whatever reason. I've got a the service manual on the way so in the meantime I will clean the carbs, sync the butterflies, get the pickup pointer synced to the roller, and get my TDC flywheel pointer set. Could you offer any insight on what the the throttle diaphragm's purpose is on these motors? [/QUOTE]
