[Healeys] FW: Still Missing under load 64 BJ8

[Dan Stromquist]

Roland:
I went home and ran it last night so I could give you accurate answers:
1.  Seems to miss more after warmed up but does miss when it is cold.
Pulling choke out does not affect anything. 
2.  It misses whether in overdrive or not but is much more noticeable under
load especially while in OD and running at above RPM 2200.  I don't dare get
it to higher RPM than 3000 it starts to miss so bad.  I tested it this
morning and it did miss without a load but does seem to as bad.
3.  The symptoms seem to subside when I let up on the load and cruise easy
at lower RPM( I baby it back home under 2000 RPM worried it will quit).
4.  I am now noticing a distinctive knock or loud ticking on start up that
goes away after 30 seconds or so.  If I rev it up the knock gets louder and
more distinctive. 
Dan

Dan-

It certainly could be either faulty new parts or not quite rightly
installed good new parts.  Barring that ....

Maybe you could clarify your symptom description.
While cold, does the car start to miss as soon as you accelerate, or
does it only start to miss after it is warmed up?
If you pull the choke out do the symptoms go away?
If you leave it out of overdrive does it miss?
If you get the engine running above 3000 rpm, do the symptoms subside?
If you drive at, say 3500 rpm for a couple of miles do you get the
symptoms?
Are the symptoms dependent on the load on the engine, as in are they
dependent on how far down your foot is on the accelerator pedal?
Do the symptoms subside if you lift up a bit on the accelerator pedal,
or does it continue to run rough after that?
