HAVE A NSR 125 WONT START WHEN DOES FOR ABOUT 3 SEC IT BACK FIRES CLEANED CARB PETROL RUNNING THROUGH PUT SEEMS TO FLOOD AFTER A BIT PLEASE HELP SO FRUSTRATED ANY ONE
Always try a new spark plug first - essential on any two stroke! The carb on these has very fine drillings and jets and personally I always use compressed air and proper carb cleaner when I'm doing these. If the engine spits back through the carb thats a sure sign of a weak mixture - if the carb floods then thats the float needle valve not seating fully.
