Almost all that I speak to with TR3's say they all run rich. Will definitely
check out  the site.

  Check out this site : A Stumble at Cruise Su's and Timing    This fellow has
gone thru a lot trying to track down a stumble at 3000 to3500 rpm on his
MGB.Even though it is a B a lot of what he discovered apllies to Triumphs as
well. There are lots of emails  from othersoffering advice and input. It seems
that distributor advance curve is critical.  I'm having stumbling issues with
my TR3 and sooty plugs so I'm taking the advice of those on the British car
forum and am sending my distributor in to Jeff at Advanced Distributors to get
the the dist curved to go with the street cam and header mods on my 3. Once I
install the improved dist I'm going to try RH(richer) needles in the SU's as
that is what is called for if you are running a header.

  Follow up on the sputtering/misfiring. Changed out the champions with NGK's
  BP6HS. (normal range) Marked improvement but still not there. Pulled the
plugs
  after 10 miles of 98% performance through the entire range. Top speed with
  little or no breakup 90 mph. All 4 plugs covered in soot. I think the
problem
  is still there causing the fouling of the plugs. It will only be a matter
of
  time. So my question is........Bentley calls for a plug cap of .032". Moss
  spec sheet for TR2 through TR4A .025". My plugs are set at .025". Any
  opinions. Tomorrow I will switch out my sport coil from my TR6, new
  distributor cap, compression check, timing. I want to change out one at a
time
  so I can zero in on the culprit. Needless to it still has the "SM" needles.
  "SL" (lean) will be in the mix.
