Hi Michael,
I would suggest that the first thing to do is short out the plug wires one
at a time to see if there is any change in the noise when a particular
cylinder is not firing.

Subject: Intermittent miss--good news and bad
Last week at Dave Russell's urging I directed my attention to the mixture.
He suggested that I start by doing nothing more than increasing the weight
of
the oil in the carb dampers, so I did this. When I went to restart the car
the starter, which had been a bit "iffy", decided to give up the ghost
entirely
and I pulled it for overhaul. I just got it back and installed it this
morning, then started the car for the first time since doing the above..
The good news is that the miss seems to be gone--no more hesitation when
accelerating from 2000 rpm's, no more "fluttering" at constant cruising
rpm's, and
it will still pull smoothly up to redline. Of course, the miss was
intermittent so this would require a bit of time on the road before I
pronounced it
gone, but that was very encouraging.
The bad news is that immediately upon start-up a new noise
appeared--something from within the engine which varies with rpm's and
sounds almost like a
stuck tappet, except it seems louder from under the car than from the top
and more
noticeable on the right side. I removed the fanbelt to see if the noise was
from either the water pump or alternator but it was still there--not a
clattering as much as a hollow thunking sound (I know this is getting
dumb!). What's
frustrating is that when I last ran the car prior to pulling the starter
there
was no noise, and the car has just sat there for a week--absolutely nothing
has been done to the car. BTW the noise is DEFINTELY NOT in the starter.
Any suggestions welcome but please don't tell me to get used to the
noise--this is my wife's car.
Best--Michael Oritt (wife's BN7)
