Senke 150-8 mixture adjusting screw for cab PZ27
Please where can I find the mixture adjusting screw on the PZ27? As I need to reduce the inflow of patrol.
Thanks in advance! |

Some carbs have it near the intake plenum/manifold-if it is here, it is a fuel screw and opening it up increases fuel. Just drill out the cap, and there should be a flathead screw hidden under there.

The fuel screw on a PZ27 is under the very front (engine side) of the carb. There is a boss that drops down (the fuel bowl is molded around it). There may well be a welch plug covering it, but it's pretty easily removed. You'll need to remove the carb to get at it.

It's true, there is a screw on the motor side, completely concealed. However, it is impossible to reach this screw with a screwdriver. What is the logic behind this? How are you supposed to regulate the fuel supply with the carburetor removed? Would the designers of this carburetor be drunk or am I simply too stupid to understand this technology

Right angle screwdriver is the way.
https://www.amazon.com/BikeMaster-Ex...dp/B001KOAD0W/ I have a similar one and use it if I ever need to fool with a bike that hasn't got a thumbscrew, i.e. it's not mine. |

flathead bit
Do you see the lower right side of bits in this set?
The smaller ones fit into the fuel screw, and these adjustment screws have low resistence to turning them by hand. Yours is apparently on the engine side of the carb, so it is a fuel screw, not an airscrew. Counterclockwise for more fuel, clockwise for less fuel.
