I get a lot of mowers AVB where people have a go at fixing them but just fit any part they can find , like this briggs 3.75hp with a Stihl coil.
The Ryobi chain saw in the briggs pic someone put the chain on backwards so they threw it out.
Found that carby you mentioned Norm on a horizontal crank shaft, Chonda pressure washer motor (6.5 hp) and this 5.5 hp horizontal shaft Chonda in the pic below.
