Syncing 3 carbs, How?
 

Could someone have pity on me and point me to some kind of resource
describing how to sync three carbs.

I goofed and turned the screws on my Force 85's carbs instead of the
manifold mounting screws (long story, suffice it to say I wasn't paying
attention). I heard something about listening through a hose or
something once before, but I have no idea what I'd be listening for. I'm
handy with tools and have a workshop (I live on a ranch, it's a
necessity). I've worked on pletny of things from shredders to tractors
and Jeeps and lawn mowers, but none of them have 3 carbs!

Check with one or more of the British sports car groups. They do
this all the time.

Any one in particular? I'm not familiar with British technology and
would have no idea who has what.

Yes. Unfortunately, most folks who've invested much time in working on a
triple rack of SU carbs are now living in "special homes", mumbling a lot,
with oatmeal dribbling down their chins. :-)

Do a quick google under "British sports car" or "SU carburetor".

Loosen all the linkage screws on the side of the carbs. With the throttle
at idle position, all the throttle plates should be down against the body.
Tighten all the linkage screws.
Now open the throttle to wide open and verify all throttle plates are
setting flat.
If one is out slightly - loosen and adjust to flat as the others.
Now back to neutral and verify all plates are the same.

Very simple on these engines.

Nevermind, I found it. However, I'm not too sure I have three of these.

Thanks! I noticed the bottom carb was not closing all the way, and I did
exactly what you suggested (it was a guess).

Somewhere I read that you could listen to the carbs through a hose. I'm
not sure why. But I tried it anyway. What I heard was the bottom one
making a more pronounced fluttering sound than the top two. What could
this be? A valve or something? Or the carb?

Would you mind helping me with another question?

I was taking the carb intake box off, while my wife was standing there
chattering at me, and therefore I stuck my screwdriver in and started
backing out the carb adjustment screws! I, apparently, thought I was
removing the airbox screws. I'm guessing these were either idle or
something else - screws. So I screwed them in gently and backed them out
2 turns, each carb. It starts and idles, but backfires and dies suddenly
if I run it up. I dunno, I goofed, and 3 carbs is a new thang fer me. I
can handle it, I just need guidance. I ordered a motor service manual
from iBoat yeaterday, but it won't arrive until the end of the week.

No, you probably don't. SU (Skinner Union) is a British carburetor common
on Brit sports cars of years ago, and still found in the restoration and
rally club world. Often found in tandem, banks of three, and occasionally a
double bank of three.

The point of the reference is not the carburetor itself, but the skill and
knowledge. Most of the people currently adept at tuning a bank of three
carburetors (regardless of manufacturer) will be found around the British
sports car environment, if they haven't yet gone mad.

Of course, you could also go to

http://www.iboats.com/boatproducts/m.../force_manual/

and order a manual for your engine.
