Here you go. Actually, I did the ATX first. My son got dust in the carburetor a few weeks ago and it's been hard to start every since. And once it was hot, forget about it. There was no visible damage to the cylinder I could see, but what the heck do I know. The new parts have so much more compression, that I do know. I also sealed the back plate and carburetor while I was in there, so I am sure that helped.

I am planning on upgrading my MT2 with the .18 parts soon. Maybe this winter or next spring before I start it up. Right now, it runs like a bat out of ****. Starts 2nd or 3rd pull even warm and idles smoothly for a full tank.

If you look at the last two pictures, this is what happens when a MT2 hits an ATX at full speed... We were horsing around on a parking lot and we got too close. My MT2 jumped the ATX nearly ripping the front tire off and slid about 6 feet on it's top, rolled onto it's wheels and came to a stop. Damage was instantly visible on the MT2. My son freaked out, but his ATX was not hurt at all except for the crease in his shell. Oh well, it happens and we had fun anyway.

*EDIT* Sorry, I did not realize the 3rd picture was so blurry, but you get the idea.
