    FS MAC 84 w/pipe, header, remote needle and 1/4 collet

    Now $350 shipped in the US I bought this motor combo new about 8-10 yrs ago. I've run about 1 1/2 gallons thru it to break it in and then had kids and the boat was just to fast and a hassle with kids and have not touched it in about 6 yrs and that's why I'm selling. At the time, I called Andy...

    Any good hobby shops near the Qaud Cities area?

    I need a new strut for my 1/8 scale and will be in Moline tomorrow. Are there any hobby shops that carry boat stuff in this area? I'll be coming from Rockford so anything fairly close would be fine. I don't really feel like driving to Al's tomorrow but if I have to I will. Thanks, Keith

    Help tuning/setup Mac 84

    OK, this is where I'm at. I don't get to run the boat that much, so I make adjustments, run it once and go home. The boat is a rocket when in gets into the turns, gets on pipe and just takes off. Enter the straights, falls off pipe and slows down. Strut is set at 1 1/4 inch down. I've run the...

    Help tuning/setup Mac 84

    Today I opened up the stinger, set the carb to run super rich and set the pipe just shy of 12 inches. The boat ran a litle better but not up to full potential. I can only get about 1/2 throttle, anything more doesn't make a difference. When the motor warms I seem to lose a little power. Should I...

    Help tuning/setup Mac 84

    initial needle setting and starting tips

    Thanks for the suggestions. When I did get the engine to run, it was acting like Andy said it should, rich with gas coming out the carb and I figured it was to rich and I would lean it out then couldn't get it restarted. I'll try it again this weekend. Any suggestions on why my flex drive seemed...

    initial needle setting and starting tips

    I've just finished building a Circus Circus and am having trouble getting the engine to run. I have a new Mac 84 with the course valve set up. What should the initial settings be at? I've managed to get it to start a couple of times but dies out after a few seconds like it ran out of gas and...
