i was in my father in laws shop and i saw an old spray rig that had a 5hp briggs flathead on it. i could tell it had been sitting awhile so i asked if i could have it and he said yea! took it home and dumped the gas and oil 1st. refilled both and it started like it was last used yesterday, i thought id have to douche the fuel lines and carb but no. the best part is it has a 1" pto{crank} shaft. im thinkin i may have to build my son a trike. ill have to get the info off the block to identify the whens and wheres but i got a freebie which is rare.:laugh:
