Throttle help needed.

[jetlag]

Ok...I actually have the throttle setup working GREAT! Pics and video at the bottom of this post.

The problem is the cable itself. I've seen pics somewhere on here or the internet, of a throttle using what looked like 1/4" tubing, compression fittings, and cable.

I got the 1/4" tubing, 1/16" cable, and some fittings. The problem? It takes about a 100lbs of force to pull the cable through the tubing unless its perfectly straight. Obviously, it won't be perfectly straight. I know not to kink it, but it will need some curves to navigate to the front of the cart.

Is the cable getting friction in the plastic tubing? Should I have used copper instead?

Thanks

It would be better to set up your bell crank so that you are pulling on it instead of pushing.

Do you use the words bell crank for everything? lol

That still doesn't help the tube situation...

What is the tubing and cable that you are using? A brake cable and case from a bike works great.

And if it is a bell crank its a bell crank.

1/4" plastic tubing like used for icemakers, and 1/16" wire cable(like on a bike). I'm guessing the cable is having friction issues with the plastic and causing it to be so hard to move...maybe 1/4" copper tubing would be better.

I have bike cables, but they are too short. I'm trying to figure out what to do with the parts I already have. 1/4" plastic tubing, 1/16" wire cable. I'm guessing friction is the cause of my problem.
