Well what do ya know!
The SPE40 fired up last night with the help of my nephew whos is a motor diagnostics mechanic. There is nothing wrong with the CDI at all![X(]
Goes to show, even after expert aero modellers looked at they agreed it was the CDI. All it was, was a flooded engine with a fuel gummed up plug. Even with a new plug. The engine needed the gunk flushed out of it and the plug burnt with a cig lighter flame to burn off all the crap.
Popped the plug back in and the engine fired up in 1 min!![X(]
So looks like the Extra260 is flying this week end.
I'll still be swaping out the new Rcexl CDI next week and doing a carb upgrade next month.[8D]
