Engine seized on 1982 Excel III

[schmitty2000]

I have an old Excel III that we just love. It isn't my newest sled, or my fastest sled, and definitely is no longer my best looking sled, but everyone that rides it seems to love it. Last weekend, when we had it out, the engine just quit. No bang, no groan, no squeal, it just turned off. When we tried to restart it, we found that it would turn over and that the pull cord was stuck. A couple years ago, we had a Phazer do the same thing and I poured some oil in the cylinders and let it sit for quite a while (weeks) and we eventually got it unseized. I have done the same thing with my Excel III for now. I don't need it fixed tomorrow, but it would be cool if I could see what I was up against this year, instead of waiting until next year. I realize that it is probably pooched, but I figure that it can't hurt to try. I won't go as far as to take the engine apart, but any tips that anyone can give me would be greatly appreciated.
Thanks
Matt

You should definately take the engine apart and it is very easy. Just a very simple puzzle to take apart and reassemble. If it stuck there is a reason. Look for that first. Cable to oil pump broke, fan belt broke, no oil in tank, ice blocking flow from tank, or a carb mixture failure. Maybe even the timing ring came loose. It will need rings for sure and probably pistons too but as much as you enjoy it you should fix it right. The sled will always be worth something as well.

I just talked to a guy in New Hampshire who has a running Excel asking $100. I need a ski bad for the same exact sled, which is why I was talking with him.
