Hi Lenny, you will always want the restrictor in place, just not always with the same size hole in it. It is a good heat insulator for the carb.

IF your bike has old gas, you can have a very bad time, if the gas is suspect, drain it, put it in a car, and fresh gas in the bike.

I've seen new, good-working bikes perform poorly with old gas.

We can go into valve clearances, and other things, but for now I would try fresh gas, and the carb adjustments and see if it will run.

Mike
