Well all the jets were clean, even the one in the left bowl. Blew everything out and re installed them. And with only 5 kicks it started !! shut it down after a couple minutes and installed the air box and filter and pipes. But it wouldn't start. A couple of farts is all. Pulled the plugs and the seamed wet but not soaked. Pulled the pipes and they were wet inside. Didn't seem like gas or oil though. And the cooling system is about empty. Any ideas?

yyup checked the tubes, there good. Bowls had fuel in them when I pulled them apart, enough? I would think so. The left cylinder bowl has the extra brass tube right?

no the restriction was in the hole the jet came out of. I cleaned the jets when I replaced the needle and seat. How is the float height measured? How do I verify the choke?

well I lost my reply so here goes again. My snapon compression tester was in need of service and the compression reading is now 115 and 120. With no pipes or carbs and only 1 reed block. I had checked the jets previously when I replaced the needle and seat. But I pulled them apart anyway. I did find some restriction in the orifice of one of the jets, so the carbs are soaking in the cleaner. Tomorrow is another day.... Steve

The bores were mic'd about 42.25 The windows were facing the reeds. I reran the compression test and the carbs were off as well as the pipes from previous testing and they were just over 100 lbs. There just seems to be little or no vacuum to draw the fuel in. But I may be wrong, 95% of my experience is with 4 strokes.

I have a 99 shee that was a recovered theft.That sat around for a few years. It was run without premix. I honed the cylinders and replaced pistons and rings. The rings have an end gap of about .014" Compression is only at 70 lbs, but the rings havent seated yet either. If I prime the cylinders it does fire but won't run. I found vacuum leaks at both reed valve blocks and added gaskets. But It still won't start. It doesn't draw in any fuel. I thought the 2 crank seals must have been beat up so I replaced them also. No joy. I injected low pressure air into one cylinder, and could see evidence of it in the second cylinder. So at this point I must ask are the two cylinders isolated from one another like all the sleds I've worked on? There no indication of a center seal or bearing in any of the part diagrams I'v looked at? Opinions welcome......
