Some of you may remember my post last week about my bad luck with 3
different vacuum advances; I thought I had that problem fixed (replaced
#3 with another from Chevy Duty), but evidently I was mistaken. During a
road trip yesterday, the truck started running extremely rough while
driving uphill (same as before). Sure enough, upon inspection it turns
out that I have killed yet another vacuum advance! While somewhat
annoying, at least I was able to start it up and get it headed head back
home, and this is where my latest problem started.
We're driving down the highway at around 65 (thanks to Patricks 3:55
rear), and start to head up a slight incline. The higher up this hill we
drove, the rougher the old girl ran (way out of time), until finally, at
the top of the hill, it just died. No sputter, no cough, no nothing
.................... just quiet. Thankfully I was able to coast over to
a farm house and get it off the highway, because its still sitting there
this morning.
Ok, heres what I know so far: I have fuel, and its getting to the carb.
I have electrical power (at least until the battery goes). I am getting
a spark at the points, but not when I try to arc a plug wire to the
block. The consensus seems to be (at least 15 people stopped to help)
that the problem lies somewhere between the distributor and the plugs.
Does this make sense? Can a dead vacuum advance kill the
rotor/condenser/coil ? The problem has got to be in that area, but I
(we) just cant figure it out.If it makes a difference, I'm running a
rebuilt 216 (has around 3000 miles on it), and everything on the engine
is either new or rebuilt.
Any suggestions?
Thanks
