well I just reread the instructions on the blower. Here is what it says and this is what I think is happening.
"I need to "boost reference the power valve" Here is what can happen if you don't. At part throttle you engine will be producing boost, but the carb will still have a high amount of vacuum under it. In this condition this high vacuum signal will not allow the power valve to operate properly and the correct amount of fuel will not be delivered for the boost provided by the blower. A lean condition can result with possible engine damage."
This is what it looks like I need to do. Anyone know anyone that is good with carbs on marine engines?
