250-500cc 2009 Wr 250 Won't Start

Rebuilt top end, was a bit of a pain to start after But ran ok and started better after warm.

It sat for 6-7 weeks, could not even get a glimmer of it to start. swapped plugs, tipped her over.
Checked spark visually and could not see anything.
Where to start from here??? Bike likely has 120 hours total, 3 heat cycles on current top end.
Carb cleaned/rebuilt and jetting seemed very close from the heat cycles, maybe some pilot adjustment required, other than that great.

Only other time I lost spark on my WR 125 i ended up swapping over to CR ignition so never really new which part failed.

Get out the multi meter mate. Start at the stator and work out, if that makes sense.

I would try a new spark plug cap first.

2 things these show a weak spark kicking speed
1st try another plug, and one that you are certain it works, like from anything running now
2nd i actually used a drill motor with a socket to spin mine over, obviously with the plug removed
before you go try anything else confirm or deny spark exists

New plug cap, cleaned carb up again, dropped pilot from 40 to 30 (been very hot here) and adjusted float to 8.7mm(was way off, must have gotten knocked around).

She fired right up, starts very easily now, will need to do a plug chop to be safe with the big pilot drop.
