Thats the old style module.
The issue you could be having could just be bad earth.
Drill out the rivets, clean up all the surfaces and re-attach the module and try that. Might save you the $$$$ a new one and post would cost.

Hi Bob,
I finally got round to trying that this weekend and also put new "O" Rings on the primer bulb cover and manifold but the result was the same. This time it only ran for about 5 minutes and then lost power (revs dropped right down).
When this happened I squeezed the rubber air supply pipe from the air filter closed (effectively choking the engine) and it picked up revs again but died back as soon as I let go. That sounds like fuel starvation so maybe it is not the electronics!
Although I've already had the plastic LM carby off and cleaned it I will do so again next weekend with more care - the problem must lie there somewhere. I must say, I'm beginning to intensly dislike that plastic carby.I've never had this kind of problem with a metal carby but this plastic thing is just so different and hard to understand.
I'll be writing "Off Forum" to Outdoorking about parts etc. and getting them to South Africa. I really need to get this engine running decently again.
Cheers,
Jerry
