Time to seek for the vanagoners (vanagonians?) expertise... What i thought initially to be a carburator problem in my '73 bus is manifesting now as a spark/distributor problem. My bus seems to be running in 3 cylinders, maybe 2. After checking the spark from the distributor with an inductive light i noticed that cylinders 2 and 4 were getting a spark unevenly and once in a while... when taking the wire plugs from cylinders 1 or 3 the engine dies, whereas if i take the wire plugs from 2 or 4 (or both), the engine doesn't change revs at all and keeps running as before. Now, if i hold #4 wire right next to its distributor hole, the cylinder starts catching sparks and the engine seems to make an effort in increasing revs... The points seem to be set correctly (dwell ~50 and remains +-1 when increasing revs). I thought it might have been a problem with the old and filthy spark plug wires that the bus had when i bought it, but this morning i replaced them with new ones and the problem is still there. I also changed the distributor cap, but didn't help. I'm not sure where to go from here... could it be a bad condenser? The distributor is a 009 mechanical advance. Any ideas? Thanks! Jose A.
