<VV> Looking for advice - GB running weirdly.

[Bryan Blackwell]

I'd suggest making sure all the parts really do match - what engine code, dist code, etc.  Just setting initial timing can be way out if it's got some other distributor in it.

He's replaced the carbs, plugs, and wires - all from Clark's.  The van had a Pertronics looking unit; but it does not have full 12 volts (I don't know offhand whether its a I or II).  It started easily and ran smoothly.
