    Without being at your trike, I would make sure you have gas first to the carb. 2nd, you have to have gas at the carb when you open the throttle cable. If you have those, plus spark, then you should be running. Have you tried any ether shot into the carb to see if you have any combustion. Not alot mind you, but enough to check to see if everything is working right. If you have piston popping, then you will have to check through your carb.

    Check the advancer is not 180 off. The easiest way to check the cam is not 180 out is to put the piston at TDC, take off the tappet covers and make sure you have clearance at both valves.. You want both lobes pointing down. Make sure you are not a tooth out with the top timing sprocket as well.
