My JD 100 Series Won't start, surprise, surprise! When turing it over I notice there is alot of fuel being blown out the muffler, What do you guys think?

I think your intake and exhaust valves are not working properly - exact engine model would help and more detail in what you have tried.

You don't give us much to work with. My thoughts are the the engine is flooding and it is time to rebuild the carb. The float needle may be sticking and the only fix for that is to replace the float needle and seat. Also, check the oil level, does it appear to be over the full mark and smell like gas? If you post back, please add engine model numbers, as my ESP is down due to our extended winter cold front.

Hello Rivets,

Yeah, I thought I'd give you a challenge. My machine is a John Deere 2005 model 102a engine is a 17 hp g4 crankshaft ohv. I think you may be right on the carb. I'm a struggleing mechaninc, in the past in stead of rebuilding the carb I've opted to purchase the entire unit. How does the cost comparison run on rebuild vs. replacement?

Replacing the float needle and seat is by far cheaper than replacing the entire carb. Also not that difficult. Take a close look at the engine for the engine model numbers and post them. I think I can find you an online service manual to help you out and when I have the model numbers I will also give you the replacement part numbers.

Please double check those numbers, can't seen to find them in my books. I am assuming you have a Briggs engine.

Just a long shot, but you "might" want to check for spark. If you have "no" spark and have been cranking and cranking, often with the choke on, the un-burned fuel has nowhere to go except out the exhaust
