Briggs powered Sears.
2 or so weeks ago my plow tractor busted the transaxle no reverse. then i got a 6 speed from my boss. then i got sick for 2 days then this last week i got to feeling well enough to go outside and do some work in it opened the 6 speed up regreased it and mixed some gear oil with the grease for extra lubrication. slapped the transaxle back together fixed a tire. so tuesday i went for a test run and the head on the 14.5 hp briggs blew the valve guides. oil everywhere out the exhaust found issue after i took the head off intake valve was covered in oil. so friday after i got paid went to scrap yard and found a 17.5 hp ohv briggs with broken rod. so i got my head for the 14.5hp. today i put it together with a new head gasket. now the engine doesnt respond to lesser throttle lol.it will run either wot or 3/4 even though the throttle position is all the way down. oh well atleast it runs. sounds really good too but i found out it sucks the gas more than before lol.
