OK, so here's what we have so far:
1. When kill wire is attached to coil = no spark.
2. When kill wire is removed from coil - spark.
3. Voltage is making it's way to the solenoid below the carburetor.
4. I can see gas shooting into the carburetor when I remove the air filter.
5. When I spray "quick start" into the carb, I do get the engine to turn a little, then a backfire, then it stops.
Kind of at a loss right now on how to get this thing going.
"I do get the engine to turn a little"..... do you mean it runs and runs normally until it is out of starting fluid?
the Spark Advance Module controls the timing of the coil, if that is bad it wont spark at the correct time. i dont know how to test it.
