Okay, so my elderly neighbor has this automatic murray lawn tractor with an 18HP Briggs and stratton V-twin engine. I has been out of commission for a few weeks and her grass has gotten high. i saw her stuggling with her self proppeled snapper high vac on her 1/2 acre lawn, so i go over with my machine to see if i can lend a hand, she says "that's ok, i need the exercise anyway", i got in a conversation about her tractor and asked if i could take a look at it, so she went over what was wrong and i took off some protective coverings from the motor and fired it up. well it didn't start, it just screeched real loud, the cooling fins moved maybe 1/2 a turn, to me it sounds like the starter is damaged, i trid turning the top of the engine by hand, and it turned, but sounded like it was rusty. this machine is only a few years ols and stored in a garrage. what do you guys think, as i hate to see her mow her entire yard with a 21" and she has too much pride to take my help in mowing.
