Man, I messed this one up. I had an old ATC70 that needed a lot of parts. Kasey helped me out with most of them (except that kill switch that I'm still waiting for), and I thought I was good to go. Finally got around to starting to put it together and found the head was cracked at the exhaust port. So, not wanting to spend a ton, I went on Ebay and bought what claimed to be an ATC70 compatible head from imotorpartsusa. Unfortunately, it sat for 3 months before I tried it out. So when I tightened the head bolts down today, the piston started hitting the head. Found the combustion chamber is too shallow. So I contacted the seller, but after 3 or 4 months, I'm guessing I'm gonna be stuck with it. Shame on me, but I was trying to get the thing running cheaply.
Does anybody make an aftermarket head that will just bolt on? I'd rather not buy anything used that needs work...
