John, Rob, my hand drill only does 1200 rpm and i doubt i can pull start it any faster than this.......

at 1200 rpm my timing is 25 degrees, but i put 10 degrees into the exel sheet

So this is because the programe can not read below this figure under that rpm, i understand this

Hiust tested with the timing light and i see the light goes out after a few hard pulls, like it stops triggering
the SCR,

but with the plug out it is fine up to 1200 rpm

i must have a trigger issue with my two boards
