It started right up and was idling better though still a loop. Yesterday it would hardly idle down. So I'll run this gas out and put a new plug in before anymore work on that. New fuel filter and tidied up all the wires and hoses. Lubed that freewheel valve plunger and it works like new. The old spark plug is from 2016 and is one range hotter than the OE spec.
That cheap hour meter I put on is working like a charm. Could not be easer. Just wrap a wire around the spark plug lead and feed it though a slot on the digital readout. No power needed.
