I have a friend who emailed me the following....

"I have a perplexing problem with the 440. I could not get it to run well, or at all mostly. It even got so I couldn't pull the starter on occasion but if I waited then I could pull. I dragged it into the shop Sat. a.m., let it warm up overnight & worked on it on Sunday.

The muffler had gas in it - lots of it. Drained the crank cases - both were full of gas. Checked the plugs, good spark, and tried again. Still didn't run.

Tried not choking it and holding the throttle wide open since it is jetted for -30 but sitting in the warm shop. It fired up first pull and revved up well but still didn't sound right and the exhaust temp gauge said the right cylinder was not firing. I took it out and drove it a short way then back to the shop. The right crank case had more gas in it.

Any thoughts on what is wrong? "



Anybody on here had this type of problem before?

I agree. Gotta check your needles and seats.

had the same problem on an indy trial. New what it was, pulled the carbs and i found a peice of white cat hair under one of the needles,, removed it and away she went!! It doesnt take much

Check your fuel pump as well - a bad pump will draw gas thru the vacuum line and will suck it inside the crank. Ive seen it happen in the past with an older sleds. WL.

Do you have to take the carbs off to do that? Also where are the needle and seats located? A picutre would be more helpful

Thought about that, but the fuel pump is on the opposite side that is filling with fuel.

heard about the neddles and seats wearing in theses older sleds and dumping fuel all the time . i had a problem like that. i shut off the fuel cutoff switch when im not riding. no problems so far. mine used to come out the exhaust after about a week of not riding.
always started though. if it was real full of gas would take 5 to 10 pulls. never filled the combustion chambers though?? i never could understand it?? a previous owner told me to shut off the fule cutoff switch and its never happened again.
