I would be concerned with the possibility of a rough running engine because the throttle is anchored to the engine mount and the engine can move separately because of the shock mounts, thereby changing the throttle setting when the engine shakes. This would give you a fluctuating rpm. The throttle cable should be anchored to the engine not the mount.

Here is a stock 1982 Super Cub throttle linkage. There is a clamp welded to a stand-off which is clamped to the engine mount. I will look in my factory pictures for a better view.

On my factory cub the throttle cable is anchored to the engine mount. With a rather weak factory part. (see Steve's pict, mine was similar) Never noticed it jumping around a whole lot.
On the hose clamp, I thought the same thing until I tried it. There is a lot of difference it hose clamps, tried a few, Breeze makes the good ones. Of course you can only see one leg of the mount in that picture.

Vans makes a bracket plate that bolts between the sump and the carb, which then gives a place to anchor the throttle, mixture, and carb heat. I believe it is depicted on their website. Oops, they don't have a picture but here is a link to the plate

appreciate the pics keep em coming. Looks like i will fab up my own bracket to support the throttle cable. I've got 4to1 exhaust and will have to include heat sheilding
Anyone run a seperate ground cable right up to the starter? Want to increase maximum power to my B/C light weight unit
See if you can include a pic of the batt cable routing no Cubs in my area
Thanks

I will get a pic today, if I remember... mad cow and all.
FYI: I don't see any tape or chafe material between the mount and the clamps or clamping system
Am I the only one that worries about the vibration causing weak spots on the mount?
Put a plastic tie around the mount for 100 hours and it takes the paint off... think about what it wears next

Talked to Kosola (the folks that overhaul engine mounts) recently. The lady there told me you would not believe what wire ties do to engine mounts.

Thin brass shims work well under those clamps.

I want to revive this thread a bit as I'm trying to run and position the carb control cables. Ware issues with metal on metal scare me little as well. It seems the factory didn't have any problems with mounting throttle cables to the engine mount, however the issue is engine vibration in the rubbers vs fixed mount causing throttle creep etc....I have an O360 which would vibrate quite a little more. Has anyone seen or have pics of that Vans bracket Bill Rusk mentioned? Any new insight on this topic or fancy new brackets, ideas, or photos? Thanks!!

fyi what ever you do, make sure with cable disconnected at throttle arm that it is relaxed in idle and full throttle position or it will immediately creep up off idle if in tension there
the crosswindsstol 180 engine install uses ONE aeroseal? winged thumbscrew hose clamp with a hole in end of wing for each cable, throttle included......STC'd 40+ years.... kinda scary looking..... so when you start over designing things, might look to whats been out there already.....

Looks a lot like some factory brackets I have. I had to fabricate my own though, when converting to a short mount on my 12. A call to Univair might be worthwhile - -

The Van's bracket goes between the carb and sump and uses an extra carb gasket. They list it to fit 0320 ande 0360's would it also fit a 0235? Are the carb/sump
bolt patterns the same for 0235 and 0320 carbs?
Thanks

Yes, the patterns are the same. Looks like a good alternative for experimental.

The bracket from Vans will not fit an O 235. The bottom of the O 235 oil sump that the bracket sits against is different than an O 320, there are also a few other subtle differences. The brackets from Vans only work if there is substantial room between the fire wall and the engine. I have an O 235 on my plane and had to fabricate brackets like those above in this thread. Took forever to get them right.
