This E-Tube carburetor is a good mixer.  As it stands now, I prefer the original PWK knockoff, but the E-Tube unit runs great with only minor tweaking.  I’m confident that I can iron out the few hiccups.  I don’t think the overly rich starting circuit would bother most folks.  I’m disappointed that I didn’t see a BIG improvement in acceleration, but I intend to keep at it and see if I can achieve at least a small improvement.  I’m also gonna see if I can change that enricher jet to a .014”.  That should be a fun project.

If you order a PWK knockoff and end up with one of these E-Tube carbs, have no fear, it will run just fine.  I hope some of you find this information useful.
