Cleaned plug, put a little gas in chamber, put new gasoline in tank and still won't start after many tries. Has the old gasoline caused the problem and do I need to clean carb?

Did it sputter? Do you have spark?

No sputter. I can't tell if I have a spark. Unit only has about 10 hours total time. No reaction at all from the engine. Bronco Bob

To test spark: remove plug and keep HV wire connected. Hold against block with an insulated object. Crank engine. Should spark.

If no spark, then change plug and look for safety switch problems.

Even if the fuel system is bad it should sputter. Spray carb cleaner should be used as "starting fluid".

Thanks! I'll give you feedback later!

OK, read the sticky at the beginning of this section. Some useful info is there for future reference.
