Hi.

I am looking for a wiring diagram for a customer's impulse 50. It won't start, has ignition spark, good crank & compression, good fuel, but doesn't appear to have voltage to electric metering solenoid on carb. We replace the voltage regulator, but don't want to continue replacing parts until we understand where voltage and grounds should and shouldn't be. If anyone could help us in this endeaver, (with a diagram or suggestions), we would be greatly thankful.
