Paul:
Great discussion thread on your web link. You are right it could be 100 =
different things. It ran much better before the carb rebuild so I am =
thinking it is in the carbs. I may go back and check all steps again =
and eliminate steps one by one. Such fun normally, except I am eager to =
get back on the road as the weather turned nicer in FL.

ok....what do you mean by 'carbs aren't running smoothly' ?
Engine is not smooth?.. sputtering? not running smooth while cruising?
An old adage.... (well two actually)
"..most carb problems are electrical..." and "..most ignition problems =
are the carbs"
Seriously though.... what method didyou use to balance the air flow at =
idle? One of those little flow meters?
NOPE NADA STOP right there. Think about it...you're sealing off the =
air to get the bubble to rise so of course the idle changes....so the =
balance tube in the manifold sucks from the other carb, bypassing the =
fuel pull.
I was finally convinced by an old mechanic and have learned from tuning =
more SU and ZS carbs than I care to mention.... use a 1/4" fuel line as =
a stethoscope ...one end in your ear..the other just up against the edge =
(not in) the carb throat. blocks minimal air... and believe me you can =
hear as little 1-2 cfm readily, but you can also hear the gurgle of the =
fuel flow! Years ago I actually gave away my flow gauges.
Eons ago..I got so fed up once I bought brand new NOS SU carbs to =
replace mine after three rebuilds of the orig units. BUT...STILL had the =
same issue...smooth speed cruising and it ran like crap. Pull the choke =
out and it ran fine, but had to push it in at closed or low speed =
throttle. Spent a year+ and hundreds of messages on various LBC =
lists....still to no avail. Than one day at a car show.... I saw a guy =
with an identical setup.... open big round K&Ns and a end plate but had =
his air filters nearly 3/4 closed off with duct tape. In the end, the =
problem was incorrect vacuum effects ...not enough air velocity when the =
piston was mid/down as there was no restriction from the air filters.
hhmmm.... ok...

Joe Curto?
Jeff Payla at Paltech - cant seem to get a response from him.
Buy new (ouch)
Others? =20
