Question on LUMPY idle (was: Lightened Flywheels)

[Larry" <rocco16v@netzero.com (Larry)]

Cory-
It would take a SERIOUS cam to make your VW 'lumpy'.  More likely, it's fuel
mixture that's off.
Pros on lightened flywheel:  quicker revving/acceleration
Cons: only the cost of the machine work. It, by itself, will not cause a
lumpy idle.
