don't walk away dumb
OK, I thought I would add more on power valves so those of you reading don't walk away stupid after reading what I previously posted.
Power valves: open as vacuum decreases to allow fuel (in addition to main jets) to enter the mixture to increase ... hmmph ... power. So based on that, if I am showing low vacuum at idle, I want a power valve with a lower number, as in opens later, at a lower vacuum, as manifold vacuum decreases as RPM increase. Hypothetically, if I am at 7" manifold at vacuum with a 8.5 power valve, the power valve is going to dump fuel and richen things up. And ideally, if I am at 7" of vacuum with a 5 power valve, power valve is shut until I open the throttle and decrease vacuum to 5", at which time the power valve opens.
(man, I sure hope I'm right)
