How long has the bike sat?
You may need a new pilot jet (corrosion)

Then check it again.
Then get old mate next door to check it....
Did you replace timing chain?
Did you have good continous spark? Tried roll start?
With good spark and fuel it will run, albeit shithouse if incorrect jetting. Which points to cam timing

Sat for over a year, carby was pulled apart and it all looks good
No chance. OK, a chance, maybe, but I doubt the carb's good after all that time. Dump the old gas, too, if you haven't already. The pilot jet is exceptionally small, and the slightest coating of varnish in the jet orifice or the passageway leading to the air stream can significantly change the effective size of the orifice. A number 45 pilot is .45mm through the metering passage. That's just over .017". A film of varnish no more than .002" thick effectively turns a #45 into a #35. That changes things...a lot.
