Kl 600 shifter kart won't fire

So I just picked up a shifter kart with n 80s? Water cooled kl600 motor.i can't get it to fire,it has very good spark and both cams are in time..I pulled carb nd exsuhst off to investigate valves all 4 move as should,but on piston up stroke it sounds like there is blow by coming from exhaust valves.i have not done compresstion test but when I put hand over intake it has very good suction.im lost.i will post pictures when I figure out how

Spark... air... fuel.

Sounds like you checked spark, checked air - at least seems like it's pumping enough to work by your hand test...
...so how about fuel?

I'm new to carbs so I'll have to defer to someone with expertise there, but I'd check some fundamental things -
Besides making sure there's [good] gas in the tank, I'd disconnect the fuel line just to make sure gas is reaching the carb, and my quick "is it the carb?" test would be to spray starter fluid straight into the carb and see if it at least starts and runs for a second or two. If it does, that would seem to isolate the issue to something in that mysterious can called a carburetor.

Just don't use much starter fluid.....it's not a great tool when used in quantities...bit like using a big hammer to fix a delicate problem.....I've watch more engines get ruined that way when some num skull thinks more is better when it doesn't fire on a simple squirt!

also checking compression will give false results due to our decompression valve release .. and you will hear a more bleed down ..
