Hello all!
I'm a newby to the snowmobile world so bear with me on this. I recently purchased a 1995 Mountain Cat 580 EXT EFI that was not running when I picked it up. I had been setting for 2.5 years so I drained all the gas, cleaned the fuel rail, cleaned the injectors and removed the rear clutch to lube it up. After all this it would not run unless the throttle was held in hence the great TSS was not working properly either. Once I took care of all these issues and took it for a 19mile ride I noticed it didn't seem to be laying down the power right and I burnt 21 liters of fuel in that short ride. It would work ok up to 55mph but then crawl slowly like it had no power past that.
Now after I wen't to take it for a small drive today it would lose all power at the clutch engagement point. When I finially got it back to the garage I looked for some posts on here that led me to test the Throttle position sensor and this is what I found: @ 0 Throttle .09v and at full throttle 1.2v. I beleive it should be a bit .06v at no throttle and 4.5v at wide open. I fooled with it for a while and decided to see if the sled would run with it disconnected which to my surprise it did and also worked like a brand new sled. Problem solved I thought but is it possible to run this sled this way or are there problems that will come up later? Also will it continue to eat gas this bad with it gone or is there an adjustment that can be made to control this?
The last thing I noticed on this sled is there is a very small leak of oil coming from the bottom of part #10. The amount of oil coming from here is very minimal but should I be concerned about that?
Thanks In advance for all of your help! I have found just about everything I have needed so far here and hope I can contribute myself someday.
