Is this good compression for a rotax type 454, 440cc engine?
-125 and 130 psi

I think the eBay guy meant 125, not -125. anything above 120 is acceptable. Below that it starts to become hard to start, etc. Did you buy that motor?

There's a shop near here that sells USED engines for $500 and up. Just an idea of what to bid, if you can afford it, and if the sled's worth it...

If I can find out about the wiring harness on the ebay engine, I will buy that. But if I dont, Ill just have to fix what I have....... and it seems that every replacement piston I find has 2 rings, could I use two 2 ringed pistons if I cant find another single ringed one?
