Hopefully someone can help me out or at least get me a little closer. I recently had my motor rebuilt and since then I have not been able to get the carb dialed in. I keep burning up plugs. I have an 1150 dominator and the air bleeds are turned out only about 7/8's turn. This keeps the transom fairly clean but the plugs are still fouling. This weekend I pulled the air bleeds to blast them clean and noticed that 1 of the idle air bleeds is a much larger size then the rest. This motor was originally built and tuned on the dyno. Does anyone see this as something that may have been done during the tuning or was it a mistake that has been causing me tons of grief ever since? Second question is in regards to jetting. This carb has mechanical secondaries and no power valve in it. Should I be running it square because of this? Because I'm not.
