i have a L reg dtr125 with a 02 reg engine and since yestaday it hasnt been starting and when it does it runs for about 10 seconds then cuts out, i got the AA out and they tryed the plug - superb spark, the fuel tap was letting fuel throught and there didnt seem to be a blockage from the tank to the carb but when spray carb cleaner into the air filter it runs ok, he said it will be the carb thats blocked and that need to take the carb off and clean it out but i wanted to know if it could be owt else before i take it apart cheers
