2015 M600 SnoPro has developed a bottom end bog to it this year. It wants to die after idling for a few seconds when accelerating to take off using casual throttle. Or if I’m going along and accelerate fast it has a bottom end bog. It feels like it loads up. It does great at mid-range too WOT but if I call for it from bottom end it loads up and sometimes dies. Sled is all stock ran EXCELLENT last year now not so good.Last year it Never Died after idling or when taking off. Please any ideas be great. Thank you!!!

Have you replaced your primary spring? Is you oil pump stuck open?

Things I would check:
Fresh fuel
C tec oil
Primary spring
Correct belt
Deflection adjusted correctly
Chain case oil level and condition
Replace park plugs
Ensure track turns freely
Check / adjust throttle cable
Remove intake and exhaust make sure both are debris free

If all these check out good you may have a reed valve failed or an electrical issue. I am not real familiar with the C-tec 600 but someone on here will be. Good luck

Solved

Ok TSS failed Again!! And I also found the temp sensor in the pipe was (1) thread from falling out not sure why this happened but I retightened it to hold it better in place with a little bit of blue Loctite. Power valves or a bit gummy so clean them as well running good now thank you thank you for all the advice this is a great site. I have saved everyone’s advice and stored it in my favorites so if somebody else has issues or if it happens to us somewhere down the line I can remember all the input everyone gave me
