30 Year Old 3HP Briggs and Stratton, 10 Year Cold Start

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.

They used these engines on the old Webb cylinder mowers - they are really great, and reliable workhorses if they are well maintained.

@blabblab1212 it was a 49cc 2 stroke with the fake engine up front and the little 49cc at the back tore it all out welded in a plate up front drilled out the holes for the engine and installed the engine and the rear mini drive axle that runs from the engine to the rear wheel

I have a 1978 briggs 2hp that sat outside for 15 years, I took it out changed the plug and the air filter then put fresh gas in it, Set the throttle because the linkage was broke and it started on the 3rd pull. amazing little motors

These make bitchin mini-bike engines. Slap a centrifugal clutch on it and away you go.
