OS .21 V-SPEC CHOKING
put about 3 litres through this engine on my buggy but for some reason for the past week it seems to choke and want to die when applying full throttle (or anything over 2/3). figured it was too rich so leaned it out but it got worse. therefore richened it but still doing it. friend says it's probably an air leak but i haven't got a clue about where to start in terms of taking the carb off etc. any tips? cheers
