Found myself in need of a gasket for the Main Nozzle Gasket for my 860 carburetor.
No tractor parts house around so decided to try the auto parts houses. Arrived at NAPA and the manager happens to have a hobby of small engines. He took one look and ordered a P/N 704637 SME BOWL GASKET for me. In that package is a bowl gasket and also a small gasket which just fits the Main Nozzle. $3.09
Hard to beat on price or availability.
