In fact our Solo 2350C has NEVER failed to start. The issue we have had with it is that it won't stop when the ignition is turned off.

This is a feature of 2-strokes which have been run at full throttle. Since every cylinder fires every shaft rotation there isn't time for hot carbon deposits in the combustion chambers to cool below auto-ignition temperature before the next compression stroke. Consequently, the engine can run as a glow-plug engine after the spark has been turned off.

I recall amusing myself with a small 2-stroke motorcycle by switching off the ignition and letting the engine run on until a large throttle change caused it to quit.
