This is very close to NOS, not much has been touched by any hand tools. Paint is on the muffler and spark plug which tells me it got ran one time due to very little discoloration on the muffler. Tank is not rusty inside, very clean. I didn’t want to do a full function test due to needing to drain oil out when I received it empty. I did test it for spark which was evident so the ignition system is good. This is a great collectible for a small engine teacher or retired teacher. The only part that has been replaced is the foam air filter, which got replaced with a factory Briggs & Stratton filter. Just a great item to display for that mechanic person in your life, thank you for your time.
