Can you advise which section I should select to review?"

"Friends & I found that the base gasket of the carburetor had a crack in it, and was leaking air (we tested it by spraying it w/ engine starter). After replacing the gasket, the engine now idles as its normally done so.

Thanks for your assistance."
