sounds like maybe the temperature compensators on the carburetors are
sticking? they're supposed to adjust the mixture when the temperature rises,
but if they're stuck, they don't. it's possible to remove and clean them,
but a bit fiddly -- check postings on the Ohio Buckeyes web site.
re the temps seen on the gauge, they sound about normal for me ... rising
slightly when you're not moving.
also, out of curiousity, what altitude were you driving? did you notice any
difference from the altitude you normally drive?

Subject: Idle (Bad) Behaviour
I took ownership of one of these roadsters about two months ago and have
enjoyed it greatly. Cruised around the Lookout Mountain Range for about 5
hours yesterday. But I do have a couple of concerns over my idle which may
or
may not be related. I am not that much of a mechanic to know.
First, when I stop the idle drops to about 600 and then climbs back up to
850.
I did not concern myself with this because it does not seem to present a
problem. I only mention it in case it is related.
The idle is fine normally. The temp stays at 3/8's when I am driving and
when
I stop, see the above. However, if I am stuck at a long light or stopped
for
a time, the temp starts to rise. As it gets to the halfway mark the idle
rises to just under 900, as the temp continues to 5/8's the idle begins to
drop until the engine dies. It cranks right back up but will die unless you
keep it revved up with the accelerator. You can continue to do this and the
temp will not go any higher. As far as I can see, just the idle problem.
All
of this happens after 3 to 5 minutes of sitting.
Once I get back on the road, the temp drops back to 3/8's and is fine unless
I
stop for an extended period again.
Any thoughts would be greatly appreciated.
