I have a murray 11hp tractor, it was running then I turned it off. I went to go and start it back up but no luck. Didn't even to nothing. I purchased a new battery, key start and no luck still. I think previous owner did some wiring of his own on it.

Hi,
If it still has the model number tag under the seat or on the rear frame, I can probably get you a parts breakdown and a wiring diagram.
Peace,
Clarke
