Fuel problem with my scooter?

[DerekP Houston]

Is it a 2 or 4 stroke motor? After confirming the fuel system is up to snuff I would also recommend replacing (not clean and regap) the plug. In some small motors the anti-pollution additives build up on the plug tip and weaken the spark. For what ever reason these deposits don't burn off like they do in an automotive 4cycle application.

In all my small motors I have moved to the more expensive but better ethanol free fuel with a maintenance dose of the Sta-bil Marine (blue) which is more effective against water in the systems, the pink stuff is ok but I have had better results from the blue. the problem centers around the ethanol's tendency to separate out and leave water in the system which reeks havoc in the fuel system. Over time because of these deposits you may have to re-adjust the carb (expecially for a 2 cycle) to make it run right.

In my very limited small engine repair I agree, spark plugs are cheap enough I just toss a new one in for 2 cycle's whenever I'm doing maintenance.

Clean carb. Replace plug. Fresh fuel. The new E10 fuel does not agree with carbs.
