The timing is dead on, the idle is pretty steady,but it keeps loading up with fuel when idling, causing a bog when accelerating from a stop. I thought about changing the jet to something smaller but someone told me that won't fix anything because the venturi is matched to that specific jet size. He said I need a new carb. What have you guys done?

Those carbs are sensitive to float adjustment and the gauge in most kits is only a starting point, but of course they don't tell you that. You will be amazed at the power when the plugs just start turning white. | | |
