[TR] Rough running TR2

Hi all
I have made some progress with my engine running problems, after some hours,
two well versed Triumph bods, and lots of high tech equipment we discovered
the following: All ignition parts in good health and working as they should.
Valve clearances as they should. Good cylinder compression on all between 168
and 170 lbs, fuel reaching both carbs which are both balanced. What was
discovered is very poor vacuum registered off the vacuum advance pipe, with
air filters removed the front piston lifting poorly when you try to increase
revs and back one is lifting but tends to "dance" a little. The car will start
no problem but does not want to rev, the only way is to very slowly and
carefully increase the revs and then it will not run clean, hunting and
wanting to die. With a colour tune on it was almost impossible to adjust to
the proper bunsen blue, with erratic colour and flashes. The consensus is an
air leak in perhaps in the inlet, spraying with WD40 did not show anything.
Any advice????
John
