The Mikuni BS32SS carburetor had a 1.3-inch bore size, with a standard idle rpm of 1,150, plus or minus 100 rpm. The fuel level measured at 0.2 inch, plus or minus 0.02 inch, and the float height measured 0.88 inch, plus or minus 0.04 inches.

I have an '81 Yamaha XS400 with dual Mikuni BS34 carbs. I cleaned the carbs once before, but then could never get it to idle right. Had to play with the choke to get it to idle normally, which I didn't want to try to fiddle with while riding.

So I'm at it again: On the top of the carb where the diaphragm is, there is one hole for the choke, and another hole for.? Mine were plugged up with crap, and I got some of it out to the point where I can see shiny brass a little ways down. Are these holes supposed to flow air or fuel, meaning I should continue my cleaning attempts, or is this just a hole leftover from the casting/assembly process? If it's supposed to flow something, why do I see brass a short ways down the hole? Download game mafia 2 tasikgame.

There's a.pdf manual there for their normal carbs, may also be one for CVs. -- Ivan Reid, School of Engineering & Design, _____________ CMS Collaboration, Brunel University.

When you have a CV carburetor that has the idle mixture screws on top, you're usually going to find the pilot air jet under the diaphragm.

It regulates the flow of air through a fixed orifice. The carb sucks gasoline up through the pilot or idle jet in the float bowl and the fuel and air mix high up in the carburetor. The idle mixture screws just control one of four idle mixture ports, the other three ports are fixed transition ports that allow the engine to get extra gasoline while vacuum drops off slightly as you just barely open the throttle. Transition ports are the CV carburetor's equivalent of the accelerator pump that a car carburetor has.
