Also check the barrel gas filters at the inputs to the carb float (part 50) Edited November 23, 200915 yr by GreenZZZ Link to comment https://www.classiczcars.com/forums/topic/33881-slows-down-when-throttle-is-opened-ignition/?&page=2#findComment-301061 Share on other sites More sharing options...
November 24, 200915 yr Author comment_301157 Posting an update - and I doubt this is the problem thats causing the symptoms above but I figured I'd post it anyhow - its about the plungers/pistons inside the carbs. The cab-side carb piston moves up and down smoothly and makes gooshy air noises just like my motorcycle carb ones. However, the front side one takes a tremendous amount of force to move up, and does not make air wooshing noises. There is no way venturi air pressure is going to move this thing.I checked both oil res. and they both seem to have AT fluid in them, although I can't tell the level (I don't see any inside but the dipstick comes up wet with it).

They worry about possible fuel pump or ignition issues. It sounds like your car is running on three cylinders.
