Hi all of you DIY’ers!
Here is a link to a great video from Don The Small Engine Doctor who clearly shows how to safely check for spark on a small engine. In the diagnosis of a small engine “no start” issue there can ONLY be 3 thinks that can go wrong to prevent the engine from starting:
- Electrical – No Spark
- Fuel – No fuel flow to create a combustible fuel air mix
- Mechanical – No compression in the cylinder – no power to drive the piston down.
Of course you can have more than one of these issues at a time to cause a “no start” condition but if you work through each one you will find what the issues are. By far a “no spark” / “no fuel” condition is the most common issue with a small engine “no start” condition.
