looks like that ole engine may have points, so theres rust under that recoil cover. it will probably have to come off anyway to lube the racheting system of the starter anyway, and maybe a new rope. If there is no spark with a new plug grounded to the engine when you pull, just switch it over to electronic ignition system, available at local mower parts house.

the carb is full of crap, so take it off and apart and soak it. soak it, soak it in liq wrench, then clean with gumout cleaner.

If it has terribly pitted aluminum, you may have to get a used carb body, maybe just a kit will fix it up. the bowl will need to be cleaned out, ansd a new gasket, maybe a float if it sinks, and maybe a needle valve if it will not clean up (i use green scrubbe). Use a guitar string or a bristle from a wire brush to clean out all the channels. the needle valve has a rubber seat, so try to go in the center thru it when using the wire to clean.

remove the air and idle screws and clean accordingly.

remove gas tank, replace all lines and clamps, if tank is plastic, clean with penetrating oil, and dry with alcohol. if metal, add a cup of deisel fuel and shake it with screws inside, shake , shake, shake upside down, sideways, etc. rinse, repeat, wash and dry. coat with oil or penetrating oil to prevent immediate rust.

that MIGHT do it.

if its a tecumseh, expect to replace the iggy system for sure. add an inline fuel filter and gas shutoff valve. fill with clean fuel
