Engine
1. All bolts checked for torque

Engine start up
1. Setup currently on ibec with a123 batteries from buddyrc fully charged
2. Chocked engine
3. Started right up at ½ throttle and died when brought just one click below ½
4. Needles richened out 1/8 turn increments till engine settled around 4200rpm and dies – low needle now at 4 turns out
5. Muffle removed to rule out any back pressure issues – no change
6. I got the engine to settle down to around 3700 rpm but then promptly died
7. Restart requires choking every time still
8. Tested with carb cleaner around all gasket areas at around 5000rpm – no change until cleaner got to throttle throat
I am wondering if maybe the issue is the timing or the ignition, either this or does anyone want to buy an engine. Anyone have any other thoughts….pulling what hair I have left out on this one
