Hello All,
I just finished fixing the problem. In addition to a leak on the intake
manifold I had a problem with one of my DCOE's. It seems that the arm that
attaches to one of the carburetors had worked itself loose and was causing
it to not close completely. I guess that would explain the 3000 rpm idle!
Right now I'm looking for 2 things:
I'm wondering if there is a source for better arms that attach to the
carburetor. I've called APT and TWM about this in the past and they didn't
have anything. I'm still using the ones that came with the carbs and now 2
of them are patched up with "Quick Steel". I'd really like to find a better
solution.
Another thing that I am looking for is *rubber* Thackery washers. I guess
that they are probably not called Thackery washers if they aren't made out
of steel, but you get the idea. I have seen these before on a car with
Delorto's and am tired of replacing the metal style washers every few
thousand miles.
Thanks again,
Don Clark

Subject: Re: Intake Manifold Gasket Q's
Don---It's somewhat unusual for the engine to go all the way up to 3,000
rpm when both throttle plates are closed. Assuming that there's no
linkage hangups, I don't think a blown intake manifold gasket alone
could cause this much of an increase. Some, maybe, as the engine has a
new supply of air in which to breath. This being the case, the spark
plug on the cylinder seeing the extra air should be snow white.
More likely the bi-pass is blown on at least one carburetor, and is
admitting air (and fuel) thru this passage. It is still unusual even
when this happens for the "idle" to stay this high. Could be a
combination of some of the above.
