    760 Backfire- HELP

    Just installed a new engine with rebuilt carbs on a XL760. I fired her up for the first time and she started in seconds. The engine idles fine but since its a new engine obviously I cant run it for long nor really rev it but just giving the throttle a light squeeze the engine backfires out the exhaust. Does that mean the carbs are too rich? Plugs look kinda wet as well.

    My 760 sometimes pops thru the exhaust, but I have mine set to run a little rich.

    I turned it down to 1 1/2 Low and left the Highs at 1/2 and the problem seemed to clear up.
