Q: No acceleration from stop or especially going up hill - w/my: 2 stroke scooter
Hi guys,
I have a 2-cycle scooter (Tomos) that has no power from start, especially after it's hot. And it's dead slow going uphill from a stop. I can go up a hill easily when I've built up speed & momentum.
The carburetor is old but I've cleaned it up as much as I could with a guitar string & carb cleaner. I've premixed the gas & oil between 32:1 - 40:1 ratio.
PLEASE HELP because it's a fun scooter and I'm trying to conserve gas when I can.
