Pulled the ignition distributor last nite, and tore it all apart. All the pieces were there and complete (not like some of the stories I have read...broken bushings, disintegrated parts, etc). The bearings were free, no lateral play. But the weights were tight and full-o-crud. Cleaned everything thoroughly...lubed with 3-in-one upon re-assembly. Set the dwell, then timed it.
Runs like a scaled dog! When I first experienced the problem I thought it seemed like an advance problem, and I changed the dried out vac advance hose....it was quite porous. The vac advance was free and moving, so I moved on to fuel. Should have gone with my gut. But now I know the fuel sys is A-OK, and it runs like a champ....can't wipe the smile off my face.
Awesome when they are running 100%...
