Tried to repower the Montgomery Ward today. Got new 8 Hp briggs in it. Leaks oil and way too fast with the pulley on old engine. My neighbor blew it up,guess engine was tired. Never tried the 8 Hp as the tractor was trade in with no transaxle. Was gonna give it to customer. Might junk it, but you know us, might try some more! It threw the drive belt on us too!
