Posted April 13, 200916 yr Is a compression gauge and a gauge used for syncing carbs the same gauge? Obviously the ends would be different, but I'm wondering about the gauge itself. I am asking because I do not have access to a set of gauges to sync my carbs, however, Harbor Freight near my house sells Compression gauges for like $5 each. If they are the same, I could just buy four of the comp gauges.
April 13, 200916 yr Moderator no, quite the opposite, compression gauges measure pressure up to around 200 psi, carb sync gauges measure vacuum as found in the carb manifold.
