Sounds like you are slopping fuel from the float bowl into the intake and flooding it out. Once the fuel evaporates it starts and run fine. Usually cause by a high float setting. Check you float level first(likely), then the float for being fuel soaked(unlikely).

 

bear 45/70

the dealer thought the float was bad, put a new one in it , also raised the float level to c if that helped , but it did not , any other info would be helpfull , this machine is being used on a farm , had a 03 400 manule never had a problem with is cutting out at all

 

He should have lowered the float level not raised it. To much fuel, plus more fuel means "still have problem". Lowering the float mean to make the float sit farther away from the base of the carb, you hold the carb body upside down(float chamber removed) and measure the distance from the top of the float to the bottom of the carb body. The greater the distance the lower the fuel level in the float bowl when carb is upright.

 

A month ago I bought a 04 500 manual, 107 miles, now has 140. Mine cuts out when the engine gets hot, when the electric fan comes on. Sometimes will not start, and backfires VERY loud, while starting. It acts like a vapor lock, tonight it happened, not as bad, but it is 40 degrees outside. Was happening at slower speeds putting around on rough trails.

 

weekend worrier i was at my dealer on sat , he wants me to briang it back in , so he can work with it some more, he said he may order a new carb for , see if that fixes the problem, being its still under warranty . if u find anything out let me know .

More than likely the problem you fellas are dealing with is a spark problem, not so much a fuel problem. The stator in the 400's and 500's goes bad once in a while, and it usually happens when riding slow, or idling , or getting warm. What happens is a wire looses connection, and looses contact when it gets warm. It causes the engine to spit sputter, and die. Minutes or hours later it will start up and run fine, but once it gets warm it does the same thing again. Hope this helps!

 

This may sound odd but I had a bit of a similar problem with my 03 500. There is a peice of foam under the seat that kept getting sucked into my intake. Try it without the seat on.

 

thanks for the info , the mechanic had mentioned something about a loose stator wire , will metion it to him .

 

i will check about the foam under neath the seat , will letu know if that helps
