"I have "pushed" the W-1's for years in multi-carb setups because the metering rod is physically connected to the throttle."
Jon,
Is there a source for good W-1 metering rods and main jets except by buying NOS carb kits or used carbs to get them?
Like Joe I have a 420S with '37 Chevy jetting on my '36 PU engine. It runs great with that jetting but it's always tempting to get it running even better. I've owned this PU since 1965 but no project is ever complete.
