Anyone have a genuine Comet 40 series driver they want to sell?

So Ive bought in total, 4 generic 40 drivers. The sheve gets cocked crooked, causing severe vibration but whats worse is it wont retract. I have to carry a small hammer to tap it and make it go back to rest. They all do this same thing after about a half hour of hard use.. Disassemble, clean and you have another good half hour of proper actuation.

Im 99% sure its the ramps and filing anything actually causes this issue to be worse as it allows the weights to rotate slightly inside the ramp. The weights have just enough room to shift and jam crooked on attempted retraction.

Now, I dont just try the driver and move on. They all get the same treatment: Filing/sanding, swap weights, springs, different lubes, parts between the 4...

Im doing some researchin, trying to find a fitting driver that has an actuation wherein everything moves in unison.

Is anyone else super hard on these generic drivers but DONT have a problem? They just work?

Interesting that you have 4 and having the same issues.

Could you post some pics of the innards?
Im curious as to what's different.
I have 2 comet 40s and have had zero issues.

The movable sheaves should be on the same side for best belt alignment. Being symmetrical it can be done this way but you need to split the difference so the belt stays as straight as possible.

Yea, I had an extra spacer on the driven, thats why it looked off to me.

So I got a chance to try a Comet driver and its working just fine.

I wonder if the cheap drivers have just enough slop for my backwards mounting to have an ill-effect.. I bet thats it.
