I had a trip over to my local - ish garden machinery centre yesterday, to see if they had a condenser. Unfortunately not, but they did have an electric ignition module thing. So I got that and fitted it today.
You join t to the wire going to the coil.
After fitting and flywheel back in place, I decided to see if it worked. I didn't replace the spark plug, just lay it on the engine. Spin the motor and a good spark. Replaced the plug then fired up the engine. Started fine and I gave it some revs. No problem except for one.
There was a pop and something flew through the air and across the workshop. I also felt drops of liquid on my face and oil spraying everywhere.
Now then, I hadn't replaced the engine cover yet and what fastens to that? Yes, the oil filler tube. The pressure with the high revs had blown it out.
Be warned!
