All,

Here=E2=80=99s another thing to ponder whilst I wait for my rebuilt =
lever shocks to arrive..

My engine will idle under the following conditions:
Idle screws are backed off all the way, not touching the plate, =
therefore not opening the throttle plate.  (In theory, they are fully =
closed.)
Mixtures nuts all the way lean. (In theory, there should be ZERO fuel =
going into the carbs.)
Both the throttle and choke are loosened from the linkage, making sure =
jets are all the way up, and throttles are not sticking
For the record, these are professionally rebuilt HS6 carbs, with super =
throttle shaft bushing, perfectly centered jets, etc.

In what is ostensibly a ZERO fuel/air mixture, how is this engine =
running?
Do these engines just have a magic power to idle when starved?

Has anyone else witnessed this on their own cars?
If so, should I do anything?  If so, what?  (other than maybe looking to =
make sure the needles/jets are matched correctly)


Kind Regards,
