Cub governor

Postby cjpenny89 » Wed Aug 19, 2020 3:03 pm

Its been may years since I visited this site. I have been giving my cub much needed attention. Touch control rebuild, plugs, wires, charging system etc.
I pulled to governor to free up the stuck throttle linkage. It was stuck solid and the only way to free it up was to pull the governor out and take it apart. After I pulled the governor I realized I am going to have to set back up the timing.
I can't remember if there is timing marks on the engine gear to governor gear? If I am lucky the mag didn't move and I will put the gear back in.
I am assuming I will have to pull the mag to get everything lined back up correctly then time it per procedure?
Thoughts and are there timing marks I need to line up?
Thanks guys!

There is a timing mark on the governor gear and the idler gear (that drives the governor). The marks should line up and be visible from the magneto side when the engine is at top dead center on the compression stroke, #1 cylinder.

Hi,
Below is a post from this week with info I wrote about timing the magneto, and pics of the timing marks on the gears.
My post is down the page.

If the governor gear oil seal is leaking, and you need to replace it, while the governor and magneto are off is a good time. I wrote info for replacing the seal on the 2nd page of the post. :)

Thanks guys I will plan on pulling the mag and line the marks up. I figured as much but didn't want to pull more apart then i needed.

It’s hard to see the timing marks with the governor oil seal in place, but it is a lot easier if you can put a visible mark on the timing marks. I used some white nail polish.
