Thank you for the advise. I really like the tip about the screwdriver. 1.5 turns seems to be what I see everywhere, and I surprised to see 2.25 in the manual. That is why I sought a confirmation.
The sled is 1997 SKi-doo Summit 670. 130+ compression on both cylinders, primer (no choke), HAC attached. Starts with 1-2 pulls. I noticed it was dying when I gave it the gas, so I thought a good carb cleaning was in order. I thought best to get some parameters nailed down before I took everything apart. I'll double check those boots
I have a tool modification that I'd like to share -- When pushing in circlips, I took an old stubby screwdriver and cut a square notch in the tip. THis helped be get a better grip on the edge of the circlip when I was pushing on it
