If it runs w/ start fluid then you have spark.
1st check to see you have fuel to lock valve and after lock valve.

2nd check if throttle butterfly opens w/ key on. If not then you have an electrical issue w/ ECU, accel pot, or wiring ect

3rd, if 1st 2 checks ok, then the problem is more than likly in the carb diaphram, (it pulls the fuel in from the convertor), or the convertor is no good.

make sure #1 wire on the ECU, tack signal, goes to neg coil.

If after you done all these checks and still have a problem, I will email some trouble shoot info.
