    Carb set up

    I just rebuilt my sons carb after a hard hit in which he split the housing. Motor runs great and is already broken in. I don't know where to set the adjustment screws for the first time out again. Any help out there on this one, thanks

    Thanks for the link, but it only gives initial high speed settings and then says this is a good setting for low speed but never mentions what that actually is. Any suggestions on initial low speed settings, approx. turns out for first time out on a motor that is already broke in but the carb had to be rebuilt due to damage, thanks guys

    The initial setting for the LSN is what it describes in the illustration, "The low-speed needle is threaded into the slide valve and is set flush (even) with the edge of the slide valve."
