I had it all the way up to 30 initial. Same outcome. Unplug the advance all the problems go away.

i had the same problem. take an old cap and drill a hole at the number 1 plug wire. shine a timing light in the hole so you can see the rotor spinning around. I guarentee when you bring up the rpm the rotor will be pointing between #1 and the next wire rather than at #1 the whole time. I sent my relutor away and had three more spots machined at different degrees to fix the problem
