Throttle cable question(s)

Problem with these Jeff is the issue if more than likely hidden inside the sheathing. My oem slides back and forth perfectly while in my hand, but the throttle has "stuck" twice in the past 2 weeks. Did it last year too.

They have a 30 day return policy, but I'm going to email them anyway and tell them it's a "known" issue.
that's true of course. We have to rely on the credibility of the seller. Generally you can see the defect when the cable is pulled all the way in either direction. I dont have an extra or it would be yours!
