440 Won't start syndrome

I haven't tried retarding the timing maybe that might work as well. I went from:

10 BTDC and it didn't want to fire
7 BTDC and it did fire after a few cranks but shuts off
5 BTDC and it does fire alittle more quicker but same issue

You ARE retarding the timing. Are you sure you are reading the marks correctly?

Going from 10BTC to 5 BTC is going in the retard direction

Makes no real sense that it starts better at 5* than 10
