RE: engine shutting down on take off
Good advice. Another thing to think about is your plumbing. What does your engine mounting look like? Where is the fuel tank in relation to the center line of the carb spraybar. Rule of thumb is the tank centerline should be about 3/8" (or so) below the carb spraybar. Different engines draw fuel at different rates which can allow a little flexibility in tank placement. You might also check for pinched fuel lines during installation. Thats happened to me on more than one occasion.
