2003 Bombardier Trax Max Engine Idle

[olefin]

Bombardier, Trax Max, 2003

Having problem with engine idle. Have to run higher RPM to keep it from dieing. Sometimes after running for half hour or so problem gets better, sometimes it doesn't. It just doesn't seem to be running right at low speeds.

Only has 250 miles.

Anyone have suggestions?

Thanks

Check fuel filter, with low miles I'd wonder why it would need carb. work but that is what is sounds like. Is the carb. where it meets the air tube underneath the seat tight?

I would clean the carb, with 250 miles and being 8 years old it may have sat for long periods of time. If the gas was not stabilized it could have messed with the carb.

Swampcat, nice one, I didn't put 2 and 2 together, good call on the age of the machine, I was thinking mileage and I agree with the carb. 100% now.

Thanks.

I agree about being a problem in the carburetor.

I don't live where it's located is the reason it has no more miles. We're usually there every month and always

run it some while there. I've used fuel stabilizer from day one.

A temporary fix would be nudge up idle speed but there is no adjustment on the carburetor that I can find.

swampcat... you say clean the carburetor. I suppose you mean tearing it down and washing in a cleaner solution?

[pete59edsel]

That is correct, tear it down.

If that does not work then you need to try to run the motor with the gas cap off. If it runs good with the cap off then it is the vent line that is under the tank that helps it breathe. Just clean that out.

BioWare,

I'll try your suggestion first.

Not sure if this has anything to with it. But I've noticed the fuel 3-way valve doesn't make any difference if it's turn to open

or closed. I once forgot to turn it to open but didn't effect the engine.
