idle, but lousy on the road. There's no deceleration enleanment, no
richening of mixture under load. I suspect the reason the carb goes
to full rich is to give some semblance of driveability, especially in
the underpowered, highway geared barges they were first used on. I've
run these carbs with the m/c solenoid disconnected, leaning the rich
stop some. Don't hope to pass an emissions test though, especially if
it requires off idle testing. Also, make sure the AIR pump isn't
pumping O2 into the manifolds or cat when you're running rich, else
you'll end up with a nice warm glow from the exhaust system. Feedback
carbs take some real skill, IMO, and the time you invest in them could
easily be replaced with time in a junkyard pulling parts for a tbi
swap. Bruce P can tell ya stories about those carbs, I've just
started working on them in the last few years.

OK hers a question for everyone who thinks a tbi swap might be worth the
trouble like off of a 305 chevy??
