I have a 1996 xlt special and I am usually pretty good at figuring stuff out for myself but this one has stumped me. My sled will start third pull when cold it won't idle but it will run great when your on the throttle except the light gets a little dim sometimes. However if I stop the sled it won't start unless yoy wait an hour and let it completely cool off. Anyone got any idea

I'll beat everyone to it... clean the carbs. pay close attention to the pilot jets. "Floss" them.

Another cheap and easy thing to check (to rule out, if for nothing else) is the gap on your throttle flipper. If it's too tight or too loose, it may kill the ignition and not allow the engine to start. It should have between 0.010" and 0.030" .

Next time it won't start, check for spark. If there's no spark, you may have a coil or stator that is failing and has an open wire as the part gets hot and expands. Once the part cools off, the wire makes contact again. Those are a bugger to find sometimes

check compression when hot?

Funny thing, my XLT would start up and run great for about 30 minutes and then it would bog out and die. Limp it back to the garage, let it just sit inside a heated garage for 30 minutes, it would start right up and run fine for about 30 minutes again and then bog out and die. Drove me crazy. Cleaned the carbs about 5-6 times each. Always had good compression. Spark was there. Then the last time I took it out, it ran great for that 30 minutes and then bogged down. I limped it back to the garage and immediately yanked the carbs off. All three carbs had a bowl full of ice.

See, each of the other times, I'd get it back to the garage and let it sit for a while to cool off before working on it. Well, the motor would cool, but the carb bowls would warm up and melt the ice.

Your theory on the coil or stator really makes sense I will have to look into that. Good thing I have both those things I'm my large part collection. Thanks!
