My father gave me his John Deere JS63 self propelled mower. It has a B&S OHV 6.75 hp motor that surprisingly runs fantastic! Considering it has sat for 5 years. Thankfully it had no fuel in it I just changed the oil that did not look bad either I just added gas and one pull it started. My question is would this motor have an air cleaner? I can't seem to find one?
