Attached is a few photos of my recently acquired 17" model 45. I bought this along with a model 33 for $80. Fired it up today after some carby cleaner and a minor cutter clutch adjustment.
There is however a problem with the Primary clutch - it appears to engage all by itself, after the engine has been running for 10 seconds or so, the cutter just engages. The thrust pad does appear quite worn out. Could that cause this ? Should I pull the engine and clutch off for a look or keep trying to adjust ?
