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.
