Funn, I *just* experienced this a couple of weeks ago. Turned out to be the plugs. I had Motocraft plugs in it and when I pulled them and replaced with Bosch, the problem went away. Symptoms were the same right down to the "holding the wire next to the distributor hole" thing. > > The points seem to be set correctly (dwell ~50 and remains +-1 when > increasing revs).

I have harped about this before, but the 009 mechanical advance is not a good choice for your '73 if it has the stock carbs. Put the stocker back in and prepare to be amazed at how much better it runs. -David ============================================================================ David Schwarze '73 VW Safare Custom Camper (Da Boat) San Diego (Actually La Mesa) '72 VW Westfalia Camper (Da Project) California, USA '73 Capri GT 2800 (Da Beast) e-mail: des@teleport.com '87 Mustang Lx 5.0 (14.17@99.34) http://www.teleport.com/~des '93 Weber WG-50 (Da Piano) ============================================================================
