Help identifying a vintage Johnson motor

[Chipster_82]

I purchased an old Johnson motor at a rummage sale. I was told it was a 5 Hp --- no engine cover -- no spark plugs. (The gas tank is on top behind the pull cord) Motor is painted dark green. I'm looking for as much info as I can get on this motor. The only numbers I found on stamped on the engine block: Serial number 955517 & Model TN28 Any idea what year ?? Horse Power ?? Which spark plugs to buy ?? etc.... I'll send a picture if someone would like to see it !! Thanks. Chip

It is a 1952-53 model 5 HP. Hopefully others can direct you to parts for the old girl..

Need the model number. But it probably is between 1980 and 1983. Please start a new thread if you have other questions and you will get better results.
