Also, I forgot to mention, this is my first two stroke. It isn't the stock carb. I think it is a 34 or 38mm Keihn(if that makes sense), but the machine isn't here to check. I ran 25:1 as I was leery about going 32:1 on a fresh piston.
I am still talking about the gasket between the jug and the crank case. After rereading shoubadaba's post, I see that there is only one gasket, but the new ones are different. The thin metal one is all that came on it stock? It just doesn't seem like it could seal.
Yes, the piston was replaced with the same size. It came with the machine. It was a Wiseco, but I can't remember the size. I measured the jug and it seemed ok. I can't remember the measurements or method(probably not accurate enough). Not sure about compression either. Although, I did measure it, it wasn't by feel. What would you consider good? My brother ripped it apart, before I checked it again. The machine would run, just not consistently and very smokey. The exhaust bridge had been relieved and the piston had the holes drilled in it.
I guess what I am asking is a leaking base gasket going to cause the same problems as leaking crank seals? I am hoping that someone will say that if I slap it back together with a new base gasket my problems may be solved, but in reality a complete teardown, bore and rebuild is required. Just seams like a waste to throw out a piston that is pretty much new, although, one of the rings is stuck - I might be able to get it loose, I haven't tried yet. I might just bolt it all together, do a leak down and compression test and then get back to you guys.
What about the oil in the balancer disappearing? After pulling the head, there was quite a bit of oil on the crank side. Is this getting sucked through the seal because of a leak, or is the seal between the two halves shot as well? Or is it from running rich/wrong mixture?
Where is the best place to get clutch puller(or what size bolt will fit the threads to use the oil method), flywheel puller and case splitter? Approximate cost? Or, am I better off just taking it in? How much should I expect to pay for labour/parts on a complete rebuild?
Thanks for all the info.
