I have a featherlite 25cc 150 mph blower that has goos spark and the carb has been cleaned yet it wont start and is flooding fuel out the exhaust?
Cleaned the carb and changed the plug . also tried heating the plug with a torch and it doesnt even try to start. checked the plug and it has great spark. i know there is fuel cus the plug gets wet and the fuel comes out the exhaust.

I seems you have answered your own question: combustion chamber flooding...so the during exhaust stroke fuel remains in the chamber, or is being sucked in from the tank. Fuel pump diaphragm is the most likely suspect part; and is a routine wear out and replacement part. After replacing, be sure to maintain according to mfr recommendation for storage (generally it's to flush tank with un-oiled fuel before storing) to avoid early wear out of fuel pumps diaphragm.
