Just ordered your book, the power valve is open until the vacuum reaches in this example 18"
of vacuum, so it is open most of the time I am guessing ( no information on vacuum at Idell )
If this P.V. was in my car it would be adding fuel all the time, unless I was going down the Baker grade in 4th gear at 100 and took my foot off the gas, waaaaaaaaaaaaaaaaaaaaaahhhhhhhhh
18" of vacuum.Tuning corroborators is becoming a lost art!
