Thread-topic: Advice on Carbs
Corey,

I've heard that a lot of these Unisyncs are now made in China and are
cheaply made.  I have one and I'm not happy with it.

If you simply want to balance the air flow between your carbs, do it
like the old timers used to do it.  Get a piece of hose and put one end
against the carb and listen to the "hiss" through the other end.  Move
it from carb to carb until the "hiss" is the same.

74 TR6


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.
