Need  some help on this;

I was adjusing it, and realized the main shaft (goes to linkage) was loose on the . I's it supposed to be? it's worn out?

That depends on what you were trying to adjust. It should be tightened once you’re done making adjustments.

Yes the linkage does wear over time any idea how old yours is?

[DTZ]

I took the shaft out, there was significant wear on the aluminum part. I fount an her used one. Hope this cures it.

Thanks for the info!

It's good you got a replacement with less spindle wear... But be aware the "4mm hole" is likely not in the same place as your previous throttle body....

I don't think we really know when this 4mm eccentric calibration was done: is it a stand alone TB setting, done when TBs were tested.... Or was it an "on-motor" calibration of the the 4mm eccentric to match the pump and linkage?? 

So just be aware that you might need to experiment with D cam position instead of relying on the 4mm rod/stop.
