Picked up one of these to repair for a bloke this one is a 19 Kohler . I know this has been broken down for at least 8 months. I guessed the battery would be flat so I told him to charge it When I picked it up he said it wouldn't start. Got home and I checked the battery, 12.5 volts but as soon as I went to start it, down to 6 volts and the second battery he gave me was not a lot better. These big motors need good cca's to crank them over
