I just completed rebuilding my carburettors (3365) on my '71 TR6, and 
could use some assistance... I can't seem to dial them in. I'm sure than 
I'm missing something (like when you've missing your eyeglasses, and 
they're on your head).

I read the various books (Bentley, Hanyes, etc) and accessed the many 
excellent wonderful knowledge bases (e.g., Buckeye Triumph. VTR, et al.). 
I serviced both units, replacing most every gasket and bushing, check 
metering needles, cleaned and rebuild to spec...
still encountered a few problems.

I can't seem to balance the Air Fflow between the two carbs. 
Engine warm, throttle linkage and choke cables disconnected, 'slow idle' 
screw at 1.5 turns (900 rpm) with the cold start/fast idle off. When I 
place the Unisyn gauge on the front carb, it stalls. Only when I increase 
up to 3,500 rpms does that plastic float move only half way up the tube 
(by-the-way, should the float be a round ball or "cup" shaped?).

Manuals/tech notes state that the mixture is too rich...
when I adjust to be leaner, still no improvement...
the float does not want to move!
Is this normal? 

Took the car fro a drive... 
she runs, but doesn't like to go fast (feels rough), and sputters when I 
turn it off.

Any advice would be appreciated.
