Engine Trouble Engine not starting no matter what

[CiniTGS]

So I checked the carb float and it was 15mm so I adjusted it to be 21mm and I still couldn't get it to start. I did get a lot of powerful sputters though, but nothing that kept running.

Correction, I realized I put the cylinder head on backwards, so after fixing that and trying it again it sputtered constantly but it wouldn't keep going. It's so close! I switched the fuel ratio back to the original instead of lean and it didn't make a difference. Any ideas?

You can put the cylinder head on in either direction. However, if you changed it and noticed a difference that might indicate that the head is leaking air.

I sealed it off though, so I'm not sure how there could be a leak. It's like constantly sputtering.

Okay, if it will kick but just not stay going, I would guess a fuel issue, probably the carb, do you still have it on the leanest setting? You could try it on a richer setting just to see if it will still kick.

I tried moving 1 lower and it was about the same, I'll try to put it to an even richer setting.

Yeah, mess around with it, it sounds like you are very close to getting it going again.

So I tried it on the richest setting and at high RPM, it feels like it's going but then the second I stop pedaling it cuts out. Like I said I sealed the head gasket so I don't think it's even possible for there to be a leak there.

Hmmmmm, wish you had a spare carb to try. I have like 2 stock NTs sitting in my garage unused.

Any ideas on what to do with mine though?
