Got it ether bad. Runs beautifully once started. No missing. No glow plug light when purchased, replaced glow plug relay, now it cycles and glow plug light works. No push button.
What I'm trying to wrap my gasoline head around, If it is a glow plug issue, then why is it firing off with the injection of ether, what is providing the fire to ignite the fuel? There's no white smoke when she is spinning over, brand new batteries, fresh fuel, with sea foam additive.
