    My advice is don't smile too big, you'll get bugs in you teeth

    Do not go out and over drive the boat until you get used to the new set up.

    Next to the oil pressure gauge, the most important thing you're going to want to watch religiously will be your fuel pressure, especially when you're heavy right foot is in action. Bad things happen fast if you go lean.

    This was ex psi canyon (Matt). I believe this was caused by a lean condition.

    How are the carb spacers working out? I haven't noticed the circle racers using those with blowers, but the guy at BDS said they have found HP improvements with 1" spacers.

    Curious about your experiences with those.

    Ps. I came across a fuel flow rate gauge recently. I'm thinking that might be a good companion to fuel pressure.

    [ as it starts to lean out you'll start to here a poping, thats no bueno[/quote]

    CAVE,you have to remember to not have any throttle input,when you are starting it. This will cause a lean condition,

    A lean condition when Pumping the throttle? Wouldn't that flood the carbs? Or did I miss some thing FARMER JOHN

    I read in another thread that when you start a blower engine you pump the throttle a few times then wait a moment. Then start it up. Once it starts you need to keep the revs at about 1100 till the engine warms up. Please correct me if this is wrong...
