Default 4 Stroke Throttle Linkage

To hook up the throttle on my OS 4 stroke I need to pass the throttle and then
bend the wire back 180 degrees to the carb.
I understand this is a common situation with 4 strokes.

I can either put 2 90 degree bends in the wire or use one curve back.
Which is better and why?

Thanks,
KW_Counter

I've used them both ways but my personal preference is to bend them in curves. I feel this works better as it gives a little bit more flex as the throttle hits its limits. But that is my personal preference and either way will work just fine.
Dubro makes a product that also takes care of this problem
You can buy from them, or you can actually make the same thing using spare parts. I have actually done that a few times and it works just fine.

Ken,

Thanks. The DuBro device looks nice but a lot of work.
Especially compared to bending wire.

Thanks,

I have not used the Du-bro. But it's pretty easy to screw and extra servo arm in the mount ahead of the throttle. Then run your rod to it, and a second rod back the carb. There is no flex in this set up either.

I have three 4 strokes and have used throttle cable on them instead of trying to loop and bend wires. Works great with no binding, and can be right up against the FW.

I have used all three methods and it depends on the application it is being applied to. I would use the single bend or the servo arm method.

a small smooth bend is also less stressful on the wire than a tight 90 degree bend. Bend in tight 90 may crack wire and cause future failure. Even Z-bends on control surfaces occasionally crack.
