So I decided to not bother with the fly wheel as I had a hard time believing it was that.... I pulled off the intake hose to the carburetor, sprayed some lubricated starter fluid and the thing started up and ran like a banshee, it barely idled but it ran beautiful.... The second I put the intake hose back on it won’t start or run, take it off, it starts beautiful again, what do you guys think?
Rebuilt top end, no start

See your tool stripped for a reason
.take the air cleaner out and clean it.try with no air cleaner.not to ride but to see if it runs.turn air mixture screw clockwise all the way in till it lightly seats.then back it out 1 and a half. Counter clockwise.try that

Counter clockwise.try thatAir cleaner is brand new, it is a k&n knock off off of eBay.... Air screw is at one and a half turns counterclockwise, I’ll take the air cleaner off tomorrow and see what it does, thanks for the advice, keep it coming, Only thing I have changed on the carburetor is i put in a 310 main jet since the builder told me to keep the airbox lid off and add the k&n.
Theres your starting point.... perhaps a rat nest, remove air filter, attach hose, (no air filter) start again. If runs, ditch air filter for a name brand one. One thing.... NO STARTING FLUID PLEASE!!! Its not needed, if it needs it something is WRONG! check it out.
ok, reattached air intake, took off the air filter....blaster ran like brand new, put the air filter back on, barely ran. I do wonder if I put too big of a main jet in there, im thinking 310 may be too big for just an open air box...everything else is stock. after running it for a few minutes up and down the street I pulled the plug and it was clean as a whistle which I thought was a bad thing...im running 32:1 premix. what do you all think??
Get a oiled foam filter.must be to much restriction in kn knock off.to clean is lean on plug.main jet comes into play around 3/4 to full throttle.if it's cold out you may need to jet up some .
When I was zipping around, I was sure to not keep it at full throttle, I went from low to high, low to high, etc. as for jetting, do you think I should go up on the pilot then? Slydog, I assume you meant go up on the pilot jet, thank you guys so much for chiming in....
Stock pilot should be fine on stock carb.you didn't get a Chinese carb with that air cleaner by chance did you
That's a good question?it was a new plug right?buy a 4 or 8 pack. Depending on how picky you are on jetting.plus a few spares are a good idea
