Eurban- You are correct, the bike and carbs are a 1978 CB750 so I do have the accellerator pump type carburetors.
Boy, i feel like a tool having adjusted the idle screws the wrong way. I just assumed that backing out the screw let more air into the mix, but I guess its the other way around! I'll definitely adjust back to the stock 1.5 turns out, and probably go to 1 or .5 turns out to lean out the mixture. (it was running rich even at the stock 1.5 turns out.) I've been hesitant to properly set these screws Eldar, because when I checked sears, the digital tachometers were a little pricey, my timing light does not have a tachometer setting, and i don't have a dwell meter. I guess i'll use my own diagnostic tools for this setting primarily being my nose
Eldar or Eurban- where is this high speed idle adjuster on the '78 carbs? I did not know that the choke automatically raised the idle setting at full choke, or that their was a high speed idle adjuster on the carbs. How does it do this? I see how the choke restricts air with the butterflies closing the carb throat, but I don't see how the choke raises the slides. If you guys could let me know where I can check for this, i'll definately do that as i'd love to not have to mess with the idle setting during every start! The PO definately messed up these carbs, when i overhauled them the accel pump was disabled for some reason, so i wouldn't be surprised if this high idle was too...
Thanks for you advice guys!!!
