markjohnson151 Posted July 23, 2015 Report Share Posted July 23, 2015 Just recently bought the carb sync tool and was wondering if anyone could tell me what the vacuum should read on a pair of stock carbs at idle and warmed up? Quote Link to comment Share on other sites More sharing options...

markjohnson151 Posted July 23, 2015 Author Report Share Posted July 23, 2015 right now they are both at "3" at idle. Just seems like it is not idling fast enough. Quote Link to comment Share on other sites More sharing options...
wayne_smith97 Posted July 23, 2015 Report Share Posted July 23, 2015 You can raise the idle. It will in turn bring up the vacuum number. Set your idle where you like it and just make sure they are pulling the same vacuum. 1 Quote Link to comment Share on other sites More sharing options...

wayne_smith97 Posted July 23, 2015 Report Share Posted July 23, 2015 Make sure you're synced at about 1/4 and 1/2 throttle also. You can check by by making sure they lift off the bottom at the same time or by using the sync tool Quote Link to comment Share on other sites More sharing options...
