My WB ute has a problem where the timing keeps changing. I have changed dizzy, carby(the prev. carby was only being fastened down in 3 spots) and new points plugs and condenser. Someone removed Elec. Ign. before I picked it up.
When its running rough it PUMPS out unburnt fuel and some burnt oil,ie black and blue smoke, embarrassing.

Could be your harmonic balancer slipping. It is a common fault on older engines.

A good check for the harmonic balancer slipping is to get the engine warm and move the dizzy each way by hand until the motor is idling the best. Tighten the dizzy down and then put the light on the balancer and see where the mark is. Take the car for a
