Hello. I've noticed that my throttle doesn't snap back that well either. I pulled the cable closer to the carb and it snaps back nice.

I also tried this, but the grip still doesn't snap back

I took the throttle apart to see how it works. When you twist the handle, it pulls a tab that pulls that cable. When I manually pull this tab, it seems to snap back fairly well. So even though it snaps back when I pull the tab, is the problem still the throttle cable? Maybe I just don't know how snappy the throttle cable should be at the top? Thanks![/quote]

It might be the rubber grip rubbing on the throttle housing. Try a little WD40 between the flat face of the grip and the housing and see if that fixes it.

I haven't lubed it yet. What lube would you suggest?

Alright, a little update. I found out that the shaft and clamps were a little gummy, so I took some WD40 to the mess and cleaned it up nice. Here's what it looks like now. Are these original parts?

When the clamp was off, the handle was snapping back like crazy. BUT when I put the clamp back on, it started getting stuck again.

So I've figured out that the clamp is actually clamping the throttle handle a little bit. If you look at the picture below, it looks like someone took the liberty of sanding down the surface of the clamp. Is this normal? Should I get a new throttle clamp? Am I clamping the clamp incorrectly to cause the throttle handle to stick? Thanks for any advice!

Update #2. The previous owner gave me some extra parts, and one of them was a different style handle. This handle had a longer metal section before the rubber grip started, which gave the clamp (the part encasing the horn button) room to not interfere with the rubber grip. When I put it on the throttle snapped back like it's supposed to do.

I spent some time trying to move the other rubber grip down the shaft, but it's on there pretty good. Anyone have any tricks on how to get a rubber grip to move? It's an original handle so I'd like to use that one.
