Well after many hours and also building a dva adapter for multimeter to test cdi reconnected cdi in unpotted format to test and she sparks. connected fuel and on 4th crank she ran. that twin pot two stroke is loud with the exhaust prop out of the water! love it when you fire an engine for the first time.
Had to pull plug caps off to stop her though.
