IML: Stumble

["Eric" <gearhead@xxxxxxxxxxx>]

Sounds like vacuum loss. Until I had the carb to manifold spacer off, I 
couldn't see how deteriorated it was. But if you've rebuilt the carb, it 
should have come w/a new spacer in the kit that you would have used as a 
replacement.
Vacuum leaks at the distributor advance, power brake booster one way valve 
seal, and any of the various vac hoses should be checked.
It seems that I lost an amount of stumble when I replaced my fully worn out 
nylon cam sprocket and timing chain.

Hi everyone. I just rebuilt my holley 4160 and everything is new and =
runnibg o.k. except for stalling off idle. It runs great at WOT, =
apparently I rebuilt a great race carb. If I lightly press the =
accelerator so I can move a little faster than idle it stumbles and =
dies.....very unnerving in traffic. The accelerator pump is new and =
installed by the book....four books to be exact. I adjusted it everyway =
I could to no avail, I even tried adjusting the accelerator pump cam. I =
cannot help but wonder if I touched something I should not have or =
improperly.  I do my best not to get angry but I have been fooling with =
it all weekend. I read everything I could in the archives like the =
suggestion to drop-kick it into the nearest trash can. It appears there =
is just not enough movement to squirt enough fuel off idle.
 Can someone please help before I beat the livin' #%#$!&%# out of the =
carb.
