[Healeys] BJ8 Carb Tuning

[Kees Oudesluijs]

Sounds like the carbs may not be properly balanced by following the 
correct procedure. I saw this problem on the TR6 of a friend of mine 
which had Strombergs (similar to SU's). After checking with the WSM it 
was clear that his mecanic did not know what he was doing. It was easily 
rectified but it took a while before I recognised the problem.

The “system” I’m referring to is the two screw assembly on the left inner side of the carb closest to the linkage.  The “screw” is the larger of the two.

Once the first question is answered and I reassemble everything, how far should they be screwed out from the stop to start effectively tuning the car?
