John-
No, I didn't see that you had won a Lindy...congratulations! Wow,
that's pretty impressive...way to go.
At first I used my original A-790, solid-wire end vernier control
that I had used with the Bing...mainly because I didn't want to wait
for a longer control to arrive from Spruce. Then when I changed to
the updraft intake manifold, it required a longer cable to make a
curve in the routing, so I had to order a new A-790. The second A-790
was a smaller diameter knob, which was nice but it seems to have more
backlash in the action. For instance, if you dial in more rpm, then
want to back off a bit, you have to back off a couple of turns of the
knob before you see any change in rpm. This is not the TBI doing
this, it is the slop in the control. I'm tempted to order another one
just to see if I got a lemon.
Another tid-bit on the TBI....don't order the smoothest, most
friction-free cable control for the mixture control. I did, and it is
TOO friction-free. It creeps on me. I think the one I got was the
A-730, and I ended up having to squeeze the housing with vice-grips,
to squish it down onto the wire, and give it some friction. I'd have
been better off with a plain ol' hardware store steel housing with
plenty of friction, or another vernier control.
