Hey yall. Im trying to get my 2003 foreman 450 es with 720 miles on it, running right after my atv repair guy "fixed it". It was running just fine. I took it to him with a leak from the carb bowl overflow. He replaced the float needle and cleaned the carb and then it didnt run at all. Then he put in a carb kit and it barely ran. So then he put in a new carb. It was about this point that i realized he had gone back to drinking heavily. The new carb is aweful and wont stay adjusted, or run over 25 mph. I think he put in one of those chinese jobs. He has thrown away the factory carb. Ive come across a new factory carb for a 2005 trx500 for $150. I cant seem to locate a factory 2003 450es carb. Does anyone know if the trx 500 carb would work in a 450es? Are honda carbs with the same 32 mm bore interchangeable? Is there any other carbs that might fit and run?
