Gerard: I agree it sounds as if your throttle cables are too snug. Also, consider looking in the distributor at the advancer system. Be sure it is loose and well lubricated so that it will return to idle timing advance as the engine speed slows down.
The big screws on the carb are for idle speed control. They simply hit on a ramp on the throttle slide. Be sure to blip the throttle open when you adjust these screws. And the cables should go well slack when the slides are resting on these needle screws.
Do you have vacuum ports on the intake manifolds? Do you have any type of vacuum adjusters for the carbs? Setting and adjusting carbs is sooooo much easier and more accurate with a vacuum display.

Wah! I've read through all the posts that showed up when I did a search for 'carburetor,' and gas is flowing happily to the carbs, valves are freshly set. I will check timing again and battery voltage, and I'll check the gas venting. I understand the pilot screws ought to be 1.5 turns out for the left carb, and 1.75 for the right, and that turning in tends to richen the mix, turning out tends to lean out the mix. Right now my problem is I can get the idle steady (pilot screws Left:1.5, Right:2) but when I goose the throttle, the revs don't want to settle back down to around 1000rpm. Comments, anyone? Thanks in advance! Gerard in Sacramento,CA How do you set the larger, more accessible 'throttle slide' screw above the pilot screw?
