So my 17aud carb arrived. It is packaged quite well with some blatant ripoff labels etc.

Fit and finish is poor with machining marks externally and sharp casting edges.

Atleast the ports are smooth

160 main jet

Slide spring. Seems fine

The cable connector came pre-rounded off! but hey for 12 bucks, ill order another

Now im just waiting for the new jets to arrive. Looking forward to giving it a go. I know this slide needle will be an issue.

All I did was deepen the hole. It was already rounded off and the casting was God awful so it's just a throw away part to me.  Just has to work for testing. If the carb works I'll buy a genuine part to replace it. Wasn't worth ruining my current cable just in case.

The bottom of the contraption captures the e-clip on the slide needle.  It sets the height of the needle.  Your enlarged hole will possibly permit the e-clip to float up & down.  You don't want the clip pinched by the contraption, you want it to have just a little wiggle.  There is a shallow counterbore in the slide that accepts the e-clip, then the contraption captures the e-clip when you install the contraption.  You want the needle free to wiggle around side-to-side, but have almost no up & down play.  Your enlarged hole might screw that up.

I've tried installing washers under the e-clip to make fine adjustments on the needle.  That doesn't work.  It wrecks the e-clip because it gets pinched.  You want the needle to be able to wiggle around side-to-side but have no movement up & down.

See how the e-clip sits nicely against the bottom of the contraption.
