Hey all, quick question. I am usung 2 vacuum gages from an auto parts store to synch my carbs. At idle the indication is very eradic and hard to read, however when you advance the throttle the gage stabilizes and gives me a pretty steady needle. Is this a common way of tuning carbs? I.E. make your adjustment and then run the throttle up to see how its balancing out? I just purchased pipes, ai removal, jets, and cold air intake and wanted to check that everything is in good working order before i dig in.
