initial timing

What's it max out for total timing? You need to find the point it stops advancing and at what RPM.

I'd set it in the 20-22 range, maybe more, 34-36 total. As long as it starts without kicking back, you should be OK staying within the total timing number. May require some work in the mechanical advance.

ok i will tinker with that this weekend looks like my dizzy came with 2 blue springs and maybe slivers extra and a black and small silver bushing.. dunno what is in them from the factory.. but i will start figureing out my total and intial and go from there so just have some body increase rpms and adjust the nob on my light keeping the light at zero till it doesnt go up any more? and see what its at so im guesing what i am trying to do set my intial then install the correct spring and bushing configuration to get my total timing at 34-36 buy 2500-3000 rpm??? so if i set my initial at 20 and want 34 for total how do i know what bushing i need lost all the paperwork to my dizzy like a dumb a but i assume i need a bushing that has 14 of advance to it to get 34??
