[QUOTE="2stroke, post: 1359188, member: 25668"] Is the plug wet? Thats an indicator of whether or not gas is making into the combustion chamber.... Try this...pull the spark plug, dump a shot glass amount of gas down the hole...quickly replace the plug and start kicking. If it fires and runs breifly then dies, then you do have a fuel delivery problem....= dirty carb... massive vacuum leak, etc. If the carb is overflowing, the needle valve is probably dirty/gummy, and so the jets are probably also gummed up. And if its always overflowing, then the bowl level is too high and that will mess you up as well [/QUOTE]
