Okay, I finally got the ignition system working properly, and now I
have a problem with the carb.
Background:
The carb is a Weber 32/36 DGAV installed on an 18V series MGB engine.
This carb is the same one that was on the engine when it was laid up a
couple of years ago. It ran fine prior to that. I have not changed
anything on it. The only thing I have done is to rebuild and clean
it. So it should not be a jet sizing problem.
The Problem:
I don't actually have it on the road yet, so all of this is coming
from playing with the engine sitting in the garage. I also let the
engine get warm to test all of this out. The problem is that the
engine spits and sputters when the throttle is opened suddenly (sudden
acceleration). If I mostly close the choke plate and hit the
throttle, it seems to work just fine. So I think it is a fuel
starvation problem.
What I do know:
1. The car idles fine.
2. The car revs smoothly to high RPMs if taken slowly.
3. Acceleration seems to work fine if the choke plates are mostly
closed.
4. The accelerator pump appears to spraying fuel into the carb (I can
hear and see it). Whether it is the proper amount, I don't know.
5. I plugged a vacuum gauge into the manifold, and got a pretty
steady number at around 20, so I figure that there is not a vacuum
leak in the intake system.
6. The timing appears to be properly set (per manual instructions).
What am I missing?
Thanks,
Rick
