Well I tore into the other 2 carbs and as I thought, there was a 146.3 on the clutch side, in fact! When I took the bowl off the main jet fell right out, it was never screwed in! Could this be the problem I had with the bog and not getting over 7500 rpm? Also the pilot jet orfice on the center carb seems plugged, can't get an even spry of cleaner to of through like the other 2, how do I clean that? Thanks!
