Prior to my last trip (report coming) I put in new coil and plug wires and a set
of the Bosch Platinum plugs (CDN Tire).  I left the gap at .7 (as the box
says, not the VW specs).  The van starts much easier and where it use to
idle at 850 it now idles at about 1200. I had no trouble with the plugs.

On my recent trip from Halifax to Lennoxville, Quebec 3,235 kms (2,010
miles) I got 24.2 MPG (or 9.71 l/100km)  which is much better than I have
gotten in the past. But I did most of the driving on 2 lane roads at about 90
kph.   That is GOOD for a 91 syncro westy with a carb.  Malcolm S
