Stan, define "idles fine". An engine can idle almost fine on three cylinders, but boy does it suck at part throttle. It will absolutely suck until over 3000. It will sit there at 800 rpm or 900, not really caring about that one jet. If all 4 were clear it would idle at 1000 or 1050.

Taking the carb tops off accomplishes two things. One, you'll know they're clean after you're done. Two, it is SUPER EASY to remove Weber idle jets in any car with the tops off.

You're right, I am asking a lot from this guy. Maybe he can do it, maybe not. Maybe it's ignition, maybe it's not. If he tries he may fail. If I was him and even a little confident, I'd try it. But I'd also have a backup plan of somebody who could bail me out.

And absolutely I know I'm correct about cleaning the WHOLE idle circuit, not just the jet. Been there, done that, LOTS.
