/diy/ - Do It Yourself

With any small engine, you just need to diagnose those 3 things, air, fuel, and spark.

Air is super easy, make sure the air filter isn’t clogged and there’s nothing jammed in there.

Spark, you can hold the spark plug against the block and pull the cord and see if it sparks. Or get an inline spark plug tester. If no spark, it’s either bad spark plug/wire, or the ignition coil, or whatever type of cutoff switch a small engine may have which cuts the ignition.

Fuel, try to start it on starter fluid. If she runs on starter fluid, you have a fuel delivery problem. Check the fuel lines, clean or rebuild or replace the carb.

It’s pretty much the same with cars except each one of those “Air, Fuel, Spark” systems has many extra parts and parameters that need to be met for it to work properly, like you have security interlocks before you get spark and electric fuel pumps and injectors. Find which system has the issue, and work through that system to find the culprit.

Sorry by check the spark I mean confirm the run switch is good and if so and no obvious damage to the plug wires, and if you still don’t have a good spark, probably the little induction coil deal.
