Got a 3HP, L valve Briggs and Stratton motor that is about 30 years old. I picked it up off a man who’s father had it in his lawnmower at one point in time. Its been sitting on his shelf in his garage for ‘many years’. So I assume around 10 years or so of sitting. Nothing amazing or spectacular here. Just cleaned the spark plug and adjusted the gap on it, adjusted the throttle, cleaned the air filter, drained the old gas in there and replaced it with some fresh gas and hoped for the best. The oil was already full and seemed alright, plus I didnt have any to replace it haha. This is the result.
