Jim
a few years back Nancy and I went via Hwy 50 and South Lake Tahoe to
Reno in our
'74 TR6 and then a rally around the North side without ever touching the
mixture. It was in August and the only issue I remember was a little
heating
around Incline Village over to Reno.

Subject: [TTSCC] High altitude mixture compensation
Importance: High
Next month Triumphest is being held at South Lake Tahoe, elevation ~6200
feet, on the way up there via Hwy 395 or 50, there are several passes
higher than that, some up to 8000 feet high. From my experience and some
hearsay, SUs, Strombergs and Zenith carburetors all need to be
readjusted to maintain decent operation at these higher altitudes.
Without adjusting them, none of these cars are going to be performing
anywhere near their best without some help.
Obviously, a mixture readjustment is the answer. However, trying to do
this on the side of the road or at a rest stop is not the easiest thing
to do. Does anyone have a short-cut rule of thumb or a guess for
compensating for each 1000 feet of altitude. For example "two flats
leaner (on the SUs) for each 100 feet", etc.
Anyone care to toss their 2 cents in on this issue, informed or
otherwise!
TIA,
Jim
PS. There is still room at the hotel for anyone that hasn't registered
