Thanks for the information on the ball and spring, however nowhere on this blog are the actual instructions for syncing the F2 carb set. I have the 4 gauge sync set and found my 1 and 4 are 5 psi light. Where are the instructions that say you need to take this apart and and turn this nut and screw which is on this part inside the carb? (replace "this part and that part" with the procedure and the name of the part or parts that are being turned or screwed in or out) There is no air jet on these carbs, only a fuel mixture jet which will not change the air pressure inside the carb throat, it only leans out or richens your mixture. If you crack the throttle and gas spurts out into the carb throat the pump is working. the 77 has no third brass tube sticking into the throat it has 2 tubes and 2 holes. Noone here that i have read seems to know how to sync these carbs. Other wise the instructions would be here in a step by step format and so far i cant find the actual procedure for syncing the keyhole carbs. Just a lot of advice on which gauges are needed. any help would be appreciated
