I hear you on the removing thought. As for the carbs.... Just one.

I'll check, but almost certain there isn't. I've had that carb on/off and apart 4 times. I don't recall the extra nipples, but I'll definitely check. I appreciate all the help so far guys. I'm hoping to have this sled running and insured for first ice.

hey glad you got it running.
what did u mean by the pulse line? is it a vacuum fed fuel tap or pump? i have seen fuel lines and vacuum lines collapse and not let enough fuel or air thru and cause problems but mostly at higher speeds/revs.
1 thing that does happen with oil injectors is the little balls and springs inside stick open and too much oil pumps, better then too little .lol
running a fuel bottle off gravity straight to the carb and by passing the tank/pet c o c k and any fuel pumps is always a good option temporary by pass the oil pump too if u want, on the yamaha oil pumps we would yank the gear that drives the oil pumps to disable them and cap off anything that needed to be.
brake cleaner, ether, or even wd 40 sprayed around the crank seals carb manifold or tube to the air box to check for leaks, metal tank? rusty?
are the correct jets in it? did someone else clean the pilot jet and put a drill bit thru it?
when u get it going we want to see a video of it purrin like a cat.....oh wait it's a ski doo.lol

(Probably wrong, but that's the line I was talking about) As for the oil injection, I've decided I'm not messing with what works!! Lol As for the carb, this machine belonged on a farm and was barely used. (Not much over 2K on it I think..... But body damage suggests different) so I don't think anything was touched on the whole sled. It was just a "boot around the farm for the kids" sled. So, from what I was told from another rider today, was that everything is doing exactly what it should be doing, re; high idle for abit, then down to proper idle. He told me it sounds like it's only a tweaking of the idle/air screws to make it run properly. I'm taking the sled to work Saturday, and working on it in a nice big, warm shop. Totally looking forward to it! I hope to upload a quick clip of the beast.

My knowledge is limited to bikes, but It should idle high around 3000 rpm and drop to 15000 - 2000 rpm. Try the vibration carb cleaning technique or take them into get ultrasonic cleaned. sometimes all it takes is a small bit of gelled fuel or rust to create big problems in a carb. The other thing is the pilot air screw itself can get a dulled tip from being cranked in to far and this tends to effect low idle problems. It would be cheap to get a new mixture crew and try it out.

Will do Steve! I already have the wheels in motion for the ultrasonic cleaner. I'm just trying to source a piece of aluminum to bend as use as the paper template. When I tore the carb down, the pilot, high and low idle screws appeared in good shape. If after this weekend I can't get it running nicely, I'll resort to the ultrasonic cleaning.
As always, thanks again.

I was referring to the air mixture screw you keep turning to get the idle lower and keep the motor running. that can create issues if it has ever been over tightened. If you just google idle screw issue on google you will know what I mean.

I quickly read this thread but might have missed the answer about registering the sled. Some MTO offices will give you a hard time and won't do it. I have registered two sleds in Barrie that had no ownership when I acquired them. You have to get a sworn affidavit, either right in their office or elsewhere. I think there is a place right next door to the Barrie office that will do the affidavit for you. Once you have sworn it belongs to you, you bought it or was given it and that it's not stolen then you will get a new ownership. You will have to buy a 2015 sticker and all in should cost about $50. Just remember, be nice because if you loose your cool you will not get the registration.

Thanks for the heads up geeman. I wonder if they'll give me flack considering I'm from Newmarket, but in Barrie to get the paperwork. Lol First things first, make sure it runs and is reliable.

Re: Cleaning, some folks swear by "SeaFoam". Done!! So guys, looks like all is good. I changed the ignition coil, installed all parts I had removed, and fired it up. Runs as good as I'd want it to run, put it that way!! Lol I ripped around the shop yard yesterday, despite getting stuck a few times with this sticky slippery snow. Other than that, it runs good. My only issue is that the idle doesn't return to base as quickly as it should. I'm now figuring some worn jets in the carb.(pilot possibly?) The next step before hardwater, is possibly doing the ultrasonic cleaning. All in all, for a transporter on the ice soley, I'm happy with it. Now all that's left is the registration thing. Hope that goes well! Or this was all just a waste of time/money. Once again, I thank all you guys who contributed to this thread with your help/ideas. Cheers! See you on the ice.
