RUSS....stand back a moment....

1   Use the Horizontal ports! [  below throttle plate ]

2    Disconnect the turnbuckle and leave it off [ for now ].

3   Get the 2 PRI.  carbs equal at IDLE....

ONLY after they're balanced....

4   Adjust the turbuckle to slip in..

5  Raise the idle to 1000-1500 [  speed doesn't matter...you're only cheking
for balance off idle! / slop in linkage] with the CROSSSHAFT!  block in place

6  check vacume balance

7   The DRIVERS  rod is the only thing you need to adjust.....get the drivers
carb to equal the pass....1  turn  either way...no more!  should do it...

Also when I used the method in the shop manual to adjust the mixture, the
needle was not steady on either side, but by backing the carb screw out some
it settled down somewhat, however I had to back the screw out much further
on the right side to get it at the same setting as the left.  It's out too
far as far as I'm concerned.  I fear it may vibrate itself out altogether.

The carb with the idle MIX  screw way out....

1   Float level is too low

2   Vacume leak somewhere...

Hope this helps...
