Title: Wandering timing?
Post by: Funkin Go-nut on August 26, 2011, 12:18:21 AM

The timing on my AC seems to move about a bit, the distributor is clamped tight and the collar for my electronic ignition is now fixed in place, any thoughts?

I'm glad I bought a timing gun/light, this one is triggered by the spark travelling through the plug lead, so no dials or knobs to turn  :)

If it is 123 ignition, curve 1 and 3 have idle control thus the ignition will move the timing to help stabilise the idle.

Is the 123ignition any better than the standard one fitted to my Bis?

The one I have is the "In distributer" type.

Is it possible that the distributer gear is slipping/not engaged correctly?

Its not massivly out, it just seems to move a bit.. :(

probably a worn distributor? any play on the distributor shaft? also check the bob weights are not sticky.
