Default Re: very bad gas mileage.

So i took apart my carb to change the setting, and the clip on the needle was caught halfway on top of and halfway under the washer with a cut in it (not sure what that washer is called) so i got it uncaught and all the way under the washer. Huge power increase, no more 4 stroking and less smoke! But now i'm worried it could be too lean. I cleaned the spark plug and went for a ride around the block, looked at the plug and saw no change in color. How far do i need to ride before check my plug?
My motorized bicycle is cooler than your Vespa, even though you can go faster.
