You didn't mention that you checked to see if the throttle discs themselves
are closing all the way. They can be tightened in place and not allow closure
leaving a large air opening.

Greetings.
I need the help of this amazing pool of Triumph experience--Dave Swauger at
The Roadster Factory suggested I write. My car--a 1960 TR 3A. Problem,
after an engine rebuild--TR 4A head; 86 mm sleeves & pistons; new Vicky
Brit
street cam, lifters, & push rods; rebuilt SU carbs; etc, I have a
smooth-running engine that will not go below 2,000 rpm. I have checked the
following:
1. The intake manifold flanges have been newly machined flat & do not leak
air (new gaskets, of course). Same with carb to intake manifold--new
gaskets,
no leakage. Insulator blocks are the replacement plastic parts which do not
leak.
2. The distributor to camshaft gear is aligned correctly and static timing
is at 4 degrees tdc.
3. The vacuum advance is holding vacuum & not leaking air. Pipe and
connection at front carb okay.
4. The carb needles are the correct normal codes.
5. The carb rebuild included new shafts and bushings--no leakage with the
"carb spray test."
5. The valve train is working as normal & is accurately gapped.
The 2,000 "idle" is smooth, not rough, but with the idle adjustment screws
entirely off their bases, the fast idle remains. (The choke enrichment cam
is
not hanging the throttle shaft.) The only thing I can now imagine is that my
installation of the cam chain is one link off. But wouldn't that result more
in an uneven idle than an idle twice as fast as normal but smooth?
Any help would be deeply appreciated. The car is a nicely restored example
and I hope to get it on the road as soon as the Ohio winter retreats. But,
there is this idle problem...
Thanks!
