By adjusting Mixture with Bosch KE3-Jetronic Mixture Adjustment
Gives a pilot control of the amount of fuel the carburetor or fuel injectors deliver to the air intake for a piston engine. The fuel and air, now a "mixture", are combusted in the cylinders. As altitude changes, air pressure changes. The pilot can optimize the fuel at different altitudes for the best engine power or for the least amount of fuel burn.
old gas or fuel mixture needs adjusting
Mixture strength in combustion refers to the ratio of fuel to air present in the air-fuel mixture. It can impact the efficiency and performance of the combustion process, with a stoichiometric mixture (ideal ratio of fuel to air) typically providing optimal results. Adjusting the mixture strength can affect factors like power output, emissions, and fuel economy in combustion engines.
You won't go far wrong using a 40/1 mixture and adjusting if you need to.
See the attached link below. The high altitude compensator opens at high elevation to allow extra air into a set of air bleeds in the carburetor to lean out the fuel mixture.
I think it happens because of the altitude and the fuel burn rate get slower as they clam higher 10,000 fleet
Small engine surging could be caused by issues such as a dirty carburetor, clogged fuel filter, or improper air/fuel mixture. To resolve this, you can try cleaning the carburetor, replacing the fuel filter, and adjusting the air/fuel mixture. If the problem persists, it may be best to consult a professional mechanic for further diagnosis and repair.
Look for a clogged air filter or a loose intake manifold bolt. If the problem is not there, the fuel mixture may be on the rich side and the carburetor needs adjusting.
one carburetter they usually have two adjusting screws one for throttle the other would be setting the right fuel mixture
