Greetings!
Bought a C-150 last weekend in pretty nice shape. Plays well. However, after bringing it home (on its side), there is a whirring sound, I think coming from the governor. I read the repair manual and loosened 2 screws on the weights to try and let them whirl into balance on their own, but that only helped a little bit. It said I might need to loosen all four screws, but I couldn't get at the other 2, so I followed the instructions and removed the motor (after letting the spring run down...), and managed to get at the screws after removing the speed adjustment arm. One of them was a little stripped, and I had to remove the entire governor to pull it out and loosen the stripped screw. Loosening those two top screws didn't really help, as the holes holding the weights to the governor shaft were not elongated like the bottom screws. But, I have sure learned a lot, LOL! After some tinkering, I have gotten the noise down a bit more, after re-installing the governor and adjusting the bearing pins on each end, fiddling with the position of the worm screw on the governor vis-avis the spindle crank. Any advice on making this adjustment? The repair manual says the success of this particular adjustment comes down to the skill and experience of the person attempting it (which I found rather amusing). I'm afraid I have only a little of the former and none of the later.
I also oiled the machine. Unfortunately I used 3-in-one, so I'll probably need to give the whole motor a thorough cleaning, which it needs anyway, frankly. But the spring is good and strong, and the reproducer works very well. Amazing machines, these are.
Cheers
