COMRADES,
Recently had the'74-6 out for the 2nd time this spring. Exiting the off ramp
on the Interstate I heard a major backfire, partial loss of power, then when
pulling off the road the engine died completely.
Turns out the brass arm had separated from its fixed position on the ignition
rotor and
was at a 45 degree angle from the 'long' axis of the rotor body. The center
rivet was intact but the locating dimple of the brass arm had risen up out of
it's position and turned the 45 degrees. Luckily I had a spare and was off on
my merry way until...........
Returning on the entrance ramp onto the interstate the engine developed a
severe miss.
Lost almost all power and pulled safely off (again). Turns out the entire
distributor had turned ccw avout 45 degrees and stopped there when the vacuum
retard unit butted up againt the engine block. Loosened the distributor clamp
and turned unit cw to where I thought the correct position should be. Somewhat
intimidating experience doing this with cars whizzing by @ 65-80 mph.
After finally returning home and re-adjusting the distributor I cannot get
the engine to accelerate smoothly on all 6 cylinders from a standstill. Engine
idles fine @ approx. 900/1,000 rpm's but hesitates when reving up from idle and
upon acceleration (without backfiring). Adjustment clamp is tight.
Did I cause any engine damage when the distributor turned the 45 degrees ccw
upon accelerating on the I-S? May this be only a incorrect timing issue or
maybe some other demon lurking? Also, is there a simple test to determine if
the distributor cap may be shorting out causing the hesitation and missing?
Any help for this novice on tpossible cures is always appreciated.
THANKS
