Yard Machines push mower I bought off FB marketplace for $20, 190cc Briggs, guy said he tried cleaning the carb with no success and even threw in a new carb. Planned on keeping it until I went to unload it at my house and the bed was full of rust flakes. Picked it up and the deck was rusted pretty bad underneath. Took apart the carb, it was dirty beyond cleaning. Threw the new carb on, put back the semi dirty air filter and checked out the E3 spark plug and put it back in. Drained the oil and refilled with some ST syn 15W40. Cranked up first pull and runs excellent. Sold it to my neighbor for what I paid.
