I bought and emptied a can of carburetor cleaner but it didn't work the first morning. I tried the spark plug tester and everything was fine there. Fuel lines and fine too. Next time out, if I have the same problem, I'll take to a mechanic. If you think you can help, and need to make a few bucks, be my guest. I think I remember you saying something about you being a mechanic? Call me if you are interested. email me for # glowik01@hotmail.com
