    I don't know what he part is called, But it is the soft spacer that fits between the motor and exaust pipe. Basically it looks like it is melting which kind of puzzled me. Why would it be used if its not rated for high temps? Right now it looks negledigble (spelling?), but I was wondering if there would be a possible easy solution to this.

    That is the exhaust gasket and it most likely has failed

    What you are seeing that looks like it's melting is probably oil from the gas/oil mixture leaking through the failure.

    Graham,
    That part is called a gasket and I'm inclined to think that is is not melting but could be leaking oil. Some of the gaskets supplied with the kits are of questionable quality and can leak even when the exhaust pipe flange is tightened correctly. Any auto parts store can supply you with gasket material which you can cut with a good pair of sissors or snips. If you are unsure about the thickness needed take your old gasket with you. It is about 1/8th inch thick. Use the exhaust pipe flange as a guide and make the gasket match it perfectly. Cut it carefully making sure you cut out a hole in the center as big or just a little bigger than the pipe size. If you are using the kit hardware, studs, bolts, etc, be careful when retightening them. They can strip easily with over torquing. Use an anti seize compound on the threads, tighten the nuts just enough to flatten the lock washers then just a little more. If you don't feel confident making a gasket yourself you can order replacements here. ENGINE_KIT_PARTS_PAGE_2 This should get you going but keep asking if you have further problems.

    wow thanks alot...that really helps me out, the reason i said the gasket was "melting" was because it was loosing material. It was literally loosing mass around the connection

    Ya, I forgot to put one of the lock washers on a side of the exhaust and it vibrated loose and blew my gasket. No auto parts stores have gasket material in my town. O'Reily's, Advance Auto Parts, even NAPA didn't have any.. I'm just going to have to order a new one.

    I could not afford gasket material so I just cut one out of good sturdy cardboard from the back of an old notebook. I coated it with 2-stroke oil and it hasn't been a problem since.
