Just poped in a used IC igniter yesterday and it fixed the number 4 cylinder.

Number 1 cylinder was still running cooler but it was definitely lit and is no longer dropping out when its warmed up.

Ill balance the carbs later and see if that brings everything back up to spec.

 

Awesome, sounds like your almost there. Alot can cause a weak cylinder, weak spark fouled plug, dirty or poorly set carbs, etc. But at least you got her running again! Congrats on the partial fix, and good luck with the rest.
