Engine starts but shuts down
For model number 12S402-0028-F8
Hello Jack, Thank you for the question. We suggest checking to make sure the Air Filter is clean and not blocking Air Flow. You can also check and clean the Carburetor and replace the Gaskets if needed. We hope this helps!
Removed tank and drained old gas. Removed and disassembled carb. Needed new gaskets and seals, and had to clean corn syrup glaze (separated ethanol) from bowl and everywhere else with carb cleaner. Throttle linkage was de-plating/rusty. Steel wool and WD40 got it moving again. Cleaned spark plug electrode. Reassembled, poured Sea Foam in the bottom of the tank and gave it a few pulls. Let Sea Foam sit for a while, then filled the tank with Premium. Blew white smoke for a minute then ran like new. Shredded for a while, then changed the oil.
