This is an addition to a reply that I posted a few minutes ago.

I just started the engine with a spark tester attached from the plug
wire to the plug. When running the spark looks very weak and when I
trun on the mower switch the spark disappears and the engine dies.
Hmmmmm. What does this point to?
