Thanks guys, so do you think I shortened the life span of the engine? Or just have to change the piston and sleeve sooner, or it just fine?

I've heard both things I'm just looking to get the most out of my car w/o having to upgrade and/or repair. My lhs had originally said the cold weather is fine and didn't mention anything about BDC (which I followed your advice and I think I got it). To get BDCI pulled the pull start heard it click and/or compress once, then pulled alittle more and it felt "looser", is that near BDC?

Thanks again
