While tinkering with this OB the past couple weeks I've had the timing plate off at least 3 times with no problems reassembling. THIS TIME something went sideways. The carb throttle follower now wants to roll under the cam plate.
I don't know what I did different but now my throttle range is very limited.

It was in fwd for the video but the gear wouldn't affect that the cam & roller don't line up.

Can someone post a clear photo of theirs?
I can't tell a thing from that 50 yo manual.
My roller is *parallel* to the edge of the cam plate. That doesn't seem right yet it doesn't look bent or out of place.
The edge of the plate ends up sliding into the middle of the "U" between three roller & top half, then jams.

I also noticed the white nylon pivoted arm directly under that cam plate is clicking when the throttle is rotated. Didn't do that before. What does that part do?

After looking at more parts diagrams & a couple ebay listings for "cam follower" I think I know what happened (but not HOW). The cam follower is the white arm & finger which is now under my timing plate. The "roller" contacts the follower.
I need to take that damned timing plate off again and find out why that follower isn't where it's supposed to be.

Whelp... Ain't gonna happen in time to take it on my vacation that starts tomorrow.

I'm getting quicker at pulling off that timing plate. :rolleyes:
Now that I know that the roller on the throttle arm presses the cam follower against the timing cam I'll be watching that everything is lined up as I wiggle the timing plate back on.

I had removed the timing plate so that I could take apart the rotating ring and retainer that it screws to and clean all the hardened grease off. Boy is it silky smooth now as I twist the tiller!

Sounds like you have it worked out.
I can’t see your video for some reason.
It’s there I just can’t get it to play.
Enjoy your vacation
