thanks bro, let me scroll back & find it. EDIT Found it & he says that if you change timing you need to check/possibly reset RP and he said something about a possible 25 deg arc (RP) change. I looked close but could not see a vac can but the movement of the rotor tells me it is operational. I am going to call him tomorrow (got free LD on my new phone so might as well put it to use). I'll post what he says. I ain't up on the start/retard stuff he mentioned but I'm looking forward to talking with him (Joe Pando)
