Hi Guys,

Thanks for you responses.

I cleaned the main jet when rebuilding carb, and just checked it again, all good.

I replaced the starter O-ring when rebuilding.

According to the Gregory's workshop manual, the gap should be set to 0.13mm-0.20mm, so just to rule it out, I re-gapped to 0.15, checked the spark, even better than before. Still not firing.

Where should I spray the ether?

Regarding the 2 stroke engine, I refuse to mow my lawn with anything else... I still use my parents old Craftsman Deluxe which doesn't miss a beat, but I want to retire it for a full restoration. I also bought one of the last 2 Stroke Mustangs, but that is staying in the box (don't tell the Mrs that!).

I'm at a loss, I'm wondering if the misfiring did some damage. At this point I'm going to finish the assembly and take some photos before it gets damaged, intentionally or otherwise mad

NormK, before I hack away at the carb and cam, anything else I can try to rule things out? It really shouldn't be this difficult unless something is seriously wrong.

I have another running mower, so I might try swapping the carb and give it a go.

Cheers,
GT
