Howdy everybody!
I picked up this 2001 RMK 700 a couple months ago from a guy that had a small snowmobile shop... He told me he had just serviced it and it was good to go...I rode it a solid 2 days with NO issues, on the third day (didn't touch it, still has 3/4 tank from previous day) I took it out of my truck (starts first pull) and it would idle but then cuts out and dies if the throttle is touched just the slightest bit (back fires, pops, crackles, the whole nine, then dies)...
So after cleaning the carbs and replacing the spark plugs, I took it into the shop... They put 300 & 320 jets in it, set the needle to #2 position, 2.5 turns out of the A/F crew... 110 PSI on the compression (fairly low, but should still run) When I picked it up, it seemed to run ok (revving it in the parking lot)~ 5,000 ft, ~ 40 degrees...
Got it up to Vail Pass ~10,600, 20 degrees... Started it up first pull (as always) but still would only idle... Went and bought 340 and 360 jets, put the 320 and 340 jets in, drove it 100 yards, died.
Put the 340 and 360 jets in it, started it, wouldn't move... Put a rag over the airbox and the choke on, limped it back to the truck...
Then I started it, with it idling, sprayed carb cleaner all over the reed cages, the crank seals on both sides, EVERYWHERE, with no luck finding an air leak...
I'm stumped... My next step is to take all the fuel lines and pump off and check for a blockage... (I've never dabbled with this kind of fuel pump setup, so I'm open to suggestions)
Anyone have any input? Other areas for me to check?
