Getting close. Don't do several things at once. One at a time and test.
1. Tie up the riser. Make sure you have it open. Test run.
No result,
2. Get a new coil, they are cheap. Test run.
No result

3. If I and 2 don't do it, and not condenser, we have to go with gas flow. Fuel delivery problem.
Pump, tank residue, fuel filter, carb. Be sure you have gas in the tank. smile
