Here is the story so far.
Mower was running and then left for a few months. Restarted OK and run for a while until a backfire/crack sound and smoke from the auto decompressor.
Removed the decompressor and found that the diaphragm was no good; so a new replacement was fitted.
The mower did restart briefly then stopped and will not start again.
I could not help myself and decided to take the carby apart to see if I could see anything wrong.
I have cleaned and reassemble the carby but cannot get the mower to start. I have drained and changed the fuel. The spark plug get wet with fuel. When I test for a spark it will only spark if I dry and clean the plug.
The carby is black palstic and the fuel camber is white could this be early LM type?
Any suggestions would be appreciated
