John:
Without meaning to sound like a smart aXX - but seriously I think that
anyone that relies on the old sound hiss hose procedure must have their ears
examined for I do not know of anyone's sophisticated hearing that can discern
the
minute differences required to tune these carbs.
I say all this truly without meaning to insult - but sincerely to make a
point. Today there are cheap instruments available that take the guess work
out
of this process. I have used several types and found the SK synchronizer -
low flow, the best and most reliable of all. This can be viewed on

(http://www.webercarbsdirect.com/STE_SK_p/sk.htm)
The second item you really need is at least one Gunnison Colortune plug
_http://www.gadgetjq.com/ctune.htm_ (http://www.gadgetjq.com/ctune.htm)
I have two of these which I install in either the 1 &4 plug or 2&3 plug.
Now you are ready to truly fine tune your engine according to the standard
procedure replacing the hose with the synchrometer for air flow and the
ColorTune just adds a bit of accuracy to the richness mixture. The engine
will
also perform much more enthusiastically.
You will be surprised how far off your engine is tuned if you plug in these
instruments and take initial readings - it will blow your mind.
I hope this helps you a bit. I found out that my hearing is fading rapidly
and this overcomes these problems.

My TF was running fine. About 3 weeks ago we pulled the plugs when we
adjusted the valves. The plugs looked good - burning brown - but had some
kind of light tan deposit on them that came right off with the flick of a
fingernail.
The valve adjustment went perfectly.
Took a 300 mile trip and car ran well, but after getting a tank of new gas
in Milwaukee, it acted up slightly.
Over the next three weeks driving around home the car continued to run/start
OK, but the idle speeded up noticeably to around 1500 rpm hot.
Of course I started fooling with the carbs and things got progressively
worse instead of better.
When I start by catching a piece of paper in the throttle screws and then
turning another turn, the engine is running very fast. It can run fairly
well at 1500, but not at 800-1000 rpm. When the hiss through the hose sounds
the same for both carbs, but the exhaust note is splashy.
When I finally pulled the plugs (should have done this first) thaey were
black and had a lot of blackish deposits on them.
What I'm wondering is if the valve adjustment cause problems, whether I got
bad gas or whether something else is at play?
I haven't touched the jets - only the throttle screws. And nothing I do
seems to get the desired results.
