Anyone have a Ledsled Internal Throttle?

I just installed one recently and so far I hate it.

It's so notchy and far from being smooth. Works fine without the cable attached to the carb so I thought maybe the springs on my carb butterfly are too stiff. Removed one spring and it didn't really help the notchy feeling, it just takes less effort. I see no burrs or anything that would make it feel this way. It's so tight I feel like it's going to eventually rip the cable out of the "knarp".

It has 2 brass rollers inside that I even tried replacing with a bearing and it didn't help much.

Anyone else have luck with one of these or did I just buy really expensive scrap metal?
