What do you mean by over-revving? Did it drive fine in the past few days?

So when you start it it revs up high and wants to take off without touching the throttle?
That is correct... it is not wanting to start now.... but my son was rideing it and he said it slowly started revn more and more as he rode it....and when he pulled up i killed it and checked cables and everything looked fine...but still was doing the same so i put it in the garage...just tryn to get an ideal on what to look for..

If you follow the throttle cable it will connect to a small lever, make sure that the lever is free. There may be a spring there too, to put tension on the lever. You should be able to move it back and forth and it should go back to it's position, not just sticking there.

ok this is the last time i go off what people tell me..... the previous owner used a rag for a air breather and that was his ideal of a new air filter...so i just spent some time cleaning rag parts out of the carb,intake,and heads....runs like a champ now...lol...the snow gods must love meh...

By the sounds of it I would almost say you have a crank seal out of it. Start it up and spray starter fluid or anything that starts on fire by the clutch behind clutch on the motor if it revs up crank seals out. The other on the mag side is hard to get at but just try that. The other thing is check that the slide isnt binding up with a weak spring.

I converted my SS440 to a Mikuni 40mm carb, with a primer. THAT is the way to go, in my opinion. Easier to tune, find parts, find advice, and I suspect better performance. You need a longer throw throttle lever (or modify what you have), cable, and air filter (get rid of that clumsy airbox), but it fits in like a glove to the original boot - it's an easy switch. I had it dynoed (I race this one) and the dyno guy was very impressed (I'll just say it has more ponies than the Exciters). I did some other things to it too. Jetting is easy to dial in. You can find used carbs out there for $50- $75. With the other stuff you might sneak this conversion in for under $100.
