The motor is going good now. I found a spring under the air filter. It looked pretty loose so tightened it up now the motor runs well. The muffler is very rusted so I will replace that soon. I think the reel needs machining. The reels edges look rounded a bit.

Its a great mower for tight yards! Catcher is easy to remove and to refit. A lot smoother with less vibrations. I have read they have design fuilts. Probibly the plastic ring gear. I am very happy with it. Just hasnt got that look the model 45 has.

Where is the serial number? I wouldnt mind knowing how old this beast is..
