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.
