carb

I went on a simple 7 mile ride to go and from right.........i my motor went dead it had gas my carb is set stock and i changed the spark plug ..........now it wont start at all it just makes this horrible screeching noise like bad breaks on a car:-||

I have a RAW 66/80cc motor was running like a champ than around 180 miles into use, the bike does not accelerate past 25. I have tried new spark plugs clutch level and clutch itself appears to be fine. To describe the feeling its as I accelerate I hit 25 feels as if I am pulled to slow down...

I am a beginner when it comes to engine kits. I bought a 66cc two stroke Chinese generic brand kit, and I upgraded the carb. My old carb died on me so I bought a new one. Both of the carbs had the same problem though. The fuel ran through the carb but the air filter also got drenched in fuel...

So i'm new to motorbiking. i bought an engine off line because i thought it would be a good idea. i started putting it together yesterday and ive had nothing but problems since. just one thing after another. my problem now is when in open the valve on the gastank the carb just starts pissing gas...
