So here's the update....
I did manage to determine why the sled wouldn't start! I decided to pull the head and as soon as I did I could see that the pistons were banged up and gouged all around the edges. The rings actually didn't seem to be that bad of shape. I then pulled the cylinder block and was amazed that the sled had run at all!!! There were grooves and gouges all over the bore. The bottom end seemed to be good, no wiggle in the crank, so I left that as it was.
Fast forward to this past October, I placed an order for pistons and rings, gasket kit and a few other odds and ends. Well the order didn't arrive until the week before Christmas, bummer, not much time to get it up and running before the snow. I should also mention that I had picked up a second hand cylinder block over the summer, not in perfect condition, but it was in much better shape than the original block from my sled. I didn't have any time to work on it before the holidays for obvious reasons, so as soon as the new year landed I was working on it as much as I could. I put the new components together and checked the compression. 112 psi in one and 115 psi in the other, perfect or so I thought! I pulled and pulled but it wouldn't run. It would start every now and again but then immediately die. So I then checked the spark, it was good. By this point I was completely puzzled!! I figured I would tear the carbs apart again even though I had cleaned them before storing it last spring, it's a good thing because there were all kinds of particles and gunk in them from sitting through the summer. Put the spotless carbs back on and was certain it would now fire up. WRONG. Again I pulled and pulled with the same outcome as before. At this point I'm ready to burn it, except it isn't worth anything so it seemed kind of pointless besides giving me a bit of gratitude.
I decided to take a break from trying to get it to run, and replaced worn out suspension components and then put a newer set of bars on off of a Fusion.
I had picked these bars up last night, they came with the brake/light assembly and also the throttle control. I got a very good deal on the bars as well as the Fusion seat and tank, so I couldn't pass on it. So this morning I decided that since I had finished with my suspension that I would put on the new bars, I was trying to avoid messing with the motor! So after an hour or so I had the new bars on and a 3" riser I had also gotten. It was looking good!!! So I figured what the hell, I'd gotten the other stuff done, I'll try and pull it over a few times. Couldn't hurt right?
I pulled exactly three times, VROOM!!! I could not believe it! I let it run about a minute then shut it down. I thought must have been a fluke. So I pulled again, VROOM!!. It fired up again!?! Wow....okay. That was simple, I guess. The best I can figure is it must have had something to do with the TPS on the old throttle assembly. So now it runs, it's idling high but I'll do some adjustments and have it running great in no time. Hopefully I didn't just jinx myself!!
Thanks again for all of the help last years guys, this forum truly is the best!
