I am so sorry for the delay.

I am fighting a bad case of bronchitis, and it is kicking my butt.

This unit does not have the strongest spark the world has ever seen, so first lets make sure it is a spark issue, and not something else.

1. How long has it been since this unit was running regularly, and how long since it ran last?

2. Remove the air filter. While cranking the engine, start spraying in some carb cleaner (do not use starting fluid). Will the engine run on carb cleaner, or does it still not start?
