The manual I have doesn't show unhooking the vacuum like I thought I read somewhere. I suspect this is correct as my timing is spot on with the red mark.
I'm still suspicious of my tach. If I try to lower it to 750 is sounds really and starts funny. If I adjust it just a bit it sounds normal to me.
I've got a tach to hook up but not sure what wire I need to hook the sense wire to at the coil. Anyone know?
I did take it for a drive down the street and back and it seemed more responsive.
