[powerstrokeon40s]

Less than a year ago I purchased a crank no start 150cc fox carbide. Did a 155cc big bore kit with cam and uni intake along with perf coil new plug and gutted exhaust. Big jets in the carb as well. After all that started and ran great. Rich at idle perfect up to wot @ 40mph

Let sit for 6 months. Charged battery today and cranked for a few mins. Finally started. Right away I noticed it would die as soon as throttle is cracked. Let idle a little more to warm up a bit. Starts everytime first crank but dies right away when cracking throttle even a hair. Played with air fuel screw but no change.

Any help would be greatly appreciated. Can't wait to get it running and back it out of the trailer at the new house.
