My advise is sense it starts but dies out when you give it throttle it's from the reeds to the air filters and anything in between.
30 pilots 440 mains to start with needle clip in the middle air screw 2 turns out. IMO those carbs are too small. Soak the carbs in some gas to clean them for a day/overnight
Check the timing plate and pickup for damage and for out of tolerance for the pickup. Also check the timing key don't go past +4 unless you know what your doin.
If it was a leak down issue it should rev up and take a long time to drop down to idle
Compression should be 130-140 could be more due to porting and domes. Less just makes a hard start once it's warmed up.
A bad stator will only show its issue under load. Revving it is not under load. Check it with an ohm meter. Your clymer book has the specs.
