Hi their, My sons qaud just boggs down and stalls when you give it throttle and stalls, was running fine yesterday untill the chain came off, I tipped the qaud up on it's back and this is when my problems started, I took the air filter off as it was full of petrol cleaned it and put it back on, Changed the engine oil as it was full of petrol and cleaned the spark plug, It still cuts out after that so i cleaned the carb out and the jets but that didn't help either it can be really hard to start and once it's started it just boggs down when you give it any throttle, I've ordered a new spark plug to see if that helps, Any idea's?

Cheers j

 

sounds flooded man. Do yourself a favor and replace the spark plug and oil filter if they were soaked in gas. Also remove the sparkplug from the head and let it air out overnight. after replacing the spark plug at the very least then let us know how it runs.

 

Will do this to see if it help, Couldn't find the oil filter when changing the oil, It's a lt-z50, It runs on tick over just not with any throttle with the back brake off,
