GolfVenture Posted April 23, 2015 Share #1 Posted April 23, 2015 My friend thought he was adjusting his carb idle with this screw. I showed him that the carb idle was a fairly large round with ridges for the fingers to be able to turn. This screw he adjusted is a bit up and back-in and fits a flat head. When I pull/push on the screw/linkage on my spare carb it seems to move all the butterflys at the same time. I need to know how it impacts the functioning of the carb, and how to reset it propertly. The picture is taken from the left side and the screw is about center of the photo. Thank You for your help... Link to comment Share on other sites More sharing options...
MiCarl Posted April 23, 2015 Share #2 Posted April 23, 2015 It is one of the synchronization screws, it does not have a "specific" setting. It needs to be adjusted with a set of vacuum gauges attached to the intakes. Link to comment Share on other sites More sharing options...
Ace Posted April 23, 2015 Share #3 Posted April 23, 2015 Looks to me like it is the screw that synchronizes the right side carbs to the left side carbs. Need to perform a carburetor synchronization to reset it. Link to comment Share on other sites More sharing options...
MasterGuns Posted April 23, 2015 Share #4 Posted April 23, 2015 Since this is on the left side of the bike, this is the adjustment screw to sync #1 carb to the #2 carb. To get it back into its proper position you will have re-sync your carbs, Link to comment Share on other sites More sharing options...
GolfVenture Posted April 23, 2015 Author Share #5 Posted April 23, 2015 Thank You All. Resync is the next step I will be helping him with my carb tune... Link to comment Share on other sites More sharing options...
