a diaphragm carburetor is a carburetor that uses a low pressures to pump petrol and air into an engine. They are usually used on small two-stroke motors that power equipment such as chainsaws and garden trimmers. They have the advantage that they can tilted in any direction and still function properly.
The diaphragm carburetor is found on many small engines. These engines power everything ranging from lawn equipment, generators, and even RC aircraft. Unlike a conventional "float" style carburetor the diaphragm carburetor will operate regardless of its orientation, even upside down! The internal workings of a diaphragm carburetor are simple in design, but complicated in explanation and consequently lengthy to discuss.
Here is a link to a diagram of a Walbro WYK carburetor.
If you have an older car that has a carburetor, the accelerator pump diaphragm may be defective
yes only the repair kit parts ,not the whole assembly.. rouser 135 carburator is diaphragm type while barako is not.
Busted diaphragm in the fuel pump. Replace the fuel pump to solve this problem. Can also be a carburetor problem such as a leaking needle valve and seat or a pinhole in the carburetor float. This would require disassembly and rebuilding the carburetor.
A Briggs and Stratton L head twin engine wills pit gas out of the carburetor and flood out when starting if the diaphragm has been damaged. This will cause excessive fuel to enter the carburetor.

Sounds like that diaphragm between the tank and carburetor to me...pull tank/carb assembly from the mower, then remove the carburetor from the tank. whats in-between is the gasket/diaphragm(be sure to remove all the old material before installing the new one) that pumps the fuel up to the carburetor and into the engine. The diaphragm only cost like 2 bucks and you can change it in like 5-10 mins. Dont waste the money on taking it to a shop, as long as you have the tools to do it....
I have the same problem at the moment. Been told that it is fuel pump diaphragm
The slide and the diaphragm separate. They just fall apart. Buy new ones. Them carbs are not easy to get out. Had to replace them on mine.
It opens /closes heater duct doors and sometimes 4 barrel carburetor secondaries. It is basically a vacuum actuated servo
