Well, yeah. Assuming vaporlock could be A symptom of several possible
causes of leaning out the engine, I was jumping from (eliminating)
fuel pump problems, to possible (unrelated) float levels. Considering
it runs great at all rpm's, and in cool weather (engine hot or cold),
I find it hard to believe the floats are 'off', unless there's some
minute adjustment to compensate for if/when the gas boils in the bowls.
I don't think so, but I was wondering..

I haven't heard/seen a way to adjust floats to perfection. Help?
I've done the flip the lid over and measure float to lid when it hits
the jet. Seems sloppy to me. Nissan manual talks about sticking some
gauge thingy down the overflow hole to measure the depth of the fuel,
but I don't see how that'll work without hitting the float!
OTOH, we've demonstrated the mix is right (colortunes/exh gas
analyzer), so perhaps the floats must be right?

Fine, contrary to any claims my wife makes.. :)
I run it at 17 degs. It does ok at 15-16, altho it doesn't solve
any problems (like vaporlocking), so I run it at 17 as it seems a
little better at this altitude.
