F Cub Throttle

Postby Captain Ron » Mon Oct 10, 2016 2:38 pm

I started restoring my 1948 F Cub after it sat in my garage for 15 years. The throttle is very stiff. Any recommendations on cleaning the governor, etc...? NOTE: I have not run it yet.
I'm currently doing the Cub checklist for new owners.

Thanks,
Ron

I use Free all or WD something like that and soak the pivot shafts going into the gov. there is an oil port there also.
Works for me.

I believe you will find lots of good information about your throttle problem at this topic: viewtopic.php?f=1&t=94315&p=743791&hilit=governor+arm#p743777
Good Luck and make sure you are very patient, sometimes it takes a while. Stan

Hi,
Like they said above, all the moving parts of the throttle and throttle rod need oiling.
Here is a pic of a place that can get stuck, it is at the governor. The shaft that the arm pivots on gets dry and the arm can get tight, oil there, it is not real easy to get at. The end of the shaft is where the cotter key is. The other end of the shaft can be oiled too. Oil all the other throttle moving parts too.
This is what the arm looks like assembled on the governor, the parts pic is an exploded pic. :)
