well, sounds like a connecting rod or a wrist pin let loose! maybe a broken ring? the exciter should be an easy fix, if you do the work yourself, keep everything clean, remember how it all goes back together, maybe take some pics. with a digital camera, have the cylinders bored at a reputible shop, and automotive shop can do these also.
one thing to keep in mind, these engines were not designed to turn a high rpm, anything over 7500 is fair game on blowing one up! i know! so becareful how your clutch is set up. when i lost mine the first time, it was due to a carb intake boot being cracked(old age) so double check them!
good luck, dave
p.s. nice drawings!

Again, I agree with Dave.

Something bad happened in that right cylinder... either your piston came unglued & slammed up against your head which would smash your spark plug, or you had a piece of metal that came up to the top of your cylinder (a piece of one of your rings, most likely) that allowed the piston to smash that plug.
In any event, I'd wager that you'll have to pull your head off there & see what exactly happened to her. It should be obvious when you pull it off, my money is on the broken ring, which should be fairly inexpensive to fix.

Pick yourself up a Clymer shop manual for your sled, and you'll be all set. Take your time, follow the directions, (and my little tip: when ever you take a screw or bolt out to take something apart....once you get it apart put that screw/bolt back in its threaded hole so you don't lose any of them, and you know where they all go), and take your time.

You should be all set for next season with a new engine. Best of luck.

Good job here guys!!

ExciterMan said it just started to bog, so I would have a to think it was something got in the jug, like a piece of ring or something that was left in the engine after a service call. If it were a wrist pin or a rod that let go, it would sound big nasty.

Either way, pull the top off and you will learn.
