school me on my rebuild

[kymudhunter]

I picked up an 198? PW 50 for my nephew, and it came with a parts bike to boot. I have been unsuccesful at getting it to run, even though "it ran last summer" according to the PO. I am going to do a top end rebuild on it, but I need to find a good cylinder first, since some of the air fins are broke off. Where can I find one (none on ebay)? Also, The oil injector dosen't seem to be working so can I just pull the drive gear out and run pre-mix in it? I have been completly through the carburetor, but is there any other points that I need to hit on before doing the top end? the kill switch is broke, so can I just run a push button style on it? Any help would be awesome, Thanks.
