My Xcr only needed the choke when it was really cold out, you sure you.re not just flooding it? Also once the plugs are flooded you can't trust them. If it is flooded, take the plugs out, pull it over a few times with the throttle pinned and the key off. Walk far away from the sled and get a propane torch and heat up each of the plugs fairly warm and re-install them and try it. You might have to repeat that a few times to get it dried up. Once it starts let it run a few minutes to clean it out.

Try starting it without choking at all.
Your carbs are in need of cleaning/adjustment.
Either the needle valve is not seating properly allowing the base to flood, or the chokes (enricher circuit) are not closing completely when off.

I know it's not that cold out yet unless you're up in northern Alberta but a high mileage 1997 XLT Touring I used to own had the same issue in the cold.

Moisture (powder snow or snow dust on the trail) would freeze something up in the cleaned carbs and not allow an eazy start if I hadn't used gas line antifreeze. The only solution was to run an electric heater pointed at the carbs for a few minutes and all was good after that.

THOROUGHLY clean all the carbs with carb cleaner and compressed air. If the bowls still turn white after they dry, douse them with wd-40 and then let the aluminum soak it up and season it. Make sure you pull out all the jets and blow through the passages. You need to check the float height before buttoning up and then lastly re- synch. I would drain your tank also.

how do you check the float hight??????

**RJ Gleason** · 11-04-2009, 06:36 PM

Turn the carb over (upside down), the levers for the floats should be parallel or slightly down to the body of the carb bowl seal.
