mp dizzy help

huh???
screw vac advance.
the cap & rotor r fixed, and yes the vac advance pulls the pickup counter clockwise some to advance meanwhile the cap,rotor,disributor can not move due to being bolted down tight...so yep ...to the left it will fire.
I'm looking at a used cap right now with the burn all the way across the contact, meanwhile the locked distributor is mostly centered or at least not burnt all the way across.

Accel makes a good brass contact rotor and cap setup as does standard ignition with their HD series w/brass contacts.

nothing wrong with a dial back light...if you don't won't to use one then better get some timing tape and accurately apply it 1st finding TDC and '0' the tape there.


remember...firing marks to the left of a clockwise distributor is better than to the right cause to the right could have you spark scattering to the next contact and well...for me, that had it lighting off the end gases and scuffing the inside bottom of the cylinder.


it's all jmo, hope it helps
