1996 Ski-Doo Formula SL 500 Idle Issue
Mark it as my first forum post ever... I'm looking for some advice; I'm an avid reader of forums and could not find a solution to my problem yet.
I have a Formula SL 500 fan cooled that I picked up last week, when the sled idles it will die after about 10 seconds if not attended to. Either you have to be on the throttle giving it gas above 3500 RPM, or just a quick shot of choke, and then it’s good for another 10seconds. You can keep sled idle seemly forever, you just have to choke it for less than a second every 10sec or so.
What I did so far:
I went through and cleaned the crabs, like I do on every sled I have.
Drained the gas and oil
Refilled with premium fuel and some Sea-foam
Refilled with new oil
Tested the fuel pump
After doing this the sled behaves the exact same way as before. For some reason it just dies after 10 seconds unless you give it a quick choke shot.... And I did read some posts that said to check my sparkplugs incase too much oil was taking over the amount of gas that was getting into the motor (which I guess could be), but the plugs look great, better than a few other sleds I have... Overall the sled is very clean, and seemed to be well cared for.
Any help or suggestions would be much appreciated!
