My '49 Cub and some questions
Posted: Fri Oct 26, 2012 12:04 pm
Hello,
Thanks again for suggestions on a trailer to haul the Cub. I got it home and have some questions. We had it painted 5 years ago and when we got it back, I had to pull the magneto to clean it and noticed that the drive on the governor appears to be in the wrong place.
1. I may need to pull the governor and re-time it. What I cant figure out is how it ran for years this way since it was never pulled before. I have an older post about this. I am attaching a picture showing the crank pulley and you can see how far it is from TDC when the impulse coupling snaps. When I had the magneto out, I could tell the dots on the sprockets weren't line up.
2. In my other picture of the block, just behind the air cleaner is a vacant hole. It appears to have relatively fine threads. What goes in here?
3. The ratiator drain plug had been removed and it appears to be long gone. The manual says the plug is a 3/8 NPT but the size of the hole looks more like a 1/4" NPT (about 1/2" in diameter). I'll buy a new plug.
Anyway, here are some pictures and thanks for the help. Let me know if you need any more information.
