the Briggs is a late 80 to mid 90s Twin II 18hp . I cant find another like it anywhere. its a Cally emissions briggs engine. (designed to run on low octane gas) but with some seafoam and good gas it runs very strong. I think its for a pump or generator system of some kind. it had the button starter/kill switch mounted on the engine.
after using my 682 with a M18 in it , I feel this Twin II 18 is stronger, maybe stronger then the vanguard
