I have checked to see if it is getting fuel to the carb and it is. It doesn't seem to be getting any spark. I have an old service manual but it doesn't get into detail very good about alot of stuff especially electrical. Does anyone have any ideas on what to check and do you know where I can get an actual repair manual. Thank You.

The problem is the needle valve in your carb is partially clogged. It's not letting enough gas into your carb fast enough. You let it sit for 10 mins and it slowly fills the carb's bowl back up. Then you ride it and it empties the bowl of gas faster than the needle valve can keep it full and the snowmobile dies. Get the carb cleaned and it will fix your problem
I have to same motor with the same problem. Its the injector, it gets gummed up from the ethenal in the fuel. within the carbourator there is a little pin that is stuck and then fuel spills right out the corburator. People will tell you its the diaphram but not the case. It needs a little tap on the side of carburator and will correct itself(likely).
First check your belt for signs of wear. The belt should ride flush on close to flush with the outside diameter of the rear pully, if it is deeper than 1/8 to 1/4 inch it may be to worn to work properly.
Then, with the sled on a stand and the hood up, rev it a few times and watch the clutch and rear pully. Does the cluch stick? Does the pulley release when there is no tension on it?
Hi guy, you told me alot just now. Clean your injectors well, snowmobile 2 cycles all smoke rather heavy for a few minutes after sarting so that is comon.Caused by the oil settling in the chamber after shuting off. If not for this the cylinders would freeze up being dry. You may have some bad oil in injector also if it sat for a time without being started. Just remember, never, ever use starting fuild to start WD40 works well though. Check your plugs for correct heat range and gap, again, 2 cycles are very touchy with this also. Make sure you have proper injection pressure as well as fuel injector pressure. Fresh synthic 2cycle injection oil and go cleaning should solve your problem unless there is major problems with frozzen rings.
possibly, most likely it is either the pilot jet is plugged, requiring carb removal and cleaning, or try bypassing the throttle cutout switch, its two bullet connectors coming off the carb, just unplug them and plug the engine side together, just be sure to flip your throttle before starting ensure it is not frozen wide open, or its just an idle screw adjustment,it's a knob on the carb.
does your motor turn over or is battery dead. think you have to pull brake lever to actuate starter. if it does turn over and doesn't start. try draining carb. and to get some fresh fuel in the carb and try again. if not you may need to clean carb.
You need a richer mixture than normal in a cold engine. It sounds like your machine is too lean on the idle circuit. Turn the air screw in on each carb to richen it up. Also, verify the choke is working properly.
