Good spark from the plug but I will try a new one just in case. I should be able to compression test it when I get my kit back tomorrow (leant it out).

It does surprise me a little that non OEM tecumseh parts don't seem to feature in Google searches for spares....

Video of how it behaved after I put the head back
