Are you saying the engine will not start using crank only ? it looks ok to start and run the engine.

No engine will not start.
Sparks are uneven .use the lamp i can only se the
Mark 1 or 2times rest is way of. Lamp flashing very slow and
Sometimes faster.
When i crank ,it will ignite on 1 or 2 cyl then nothing
If i continue som small backfires can come.
Stop then try again same thing will happen.

If you do a coil test, do you get a good spark on all plugs ?

Is the missing tooth position set correctly, or at least close enough that it will be able to start ?

Are you sure everything is wired correctly ?

I have spark on all cyl. Ive seen better sparks and worse to.
One thing that struck me now .ive been using msd6al before
Maybe i did wider gap on them. Will check after work

So the system cant spark with the lower power during start.

Exactly what coils are you using, are they wired and configured correctly ?

What is battery voltage during cranking ?
