If the vacuum can is like OEM, the adjuster controls the spring rate, not the amount of advance.
Panic - ??? I'm confused
I sent a question to the seller of this unit asking if the vaccuum advance is adjustable. They replied that it was.
I assumed/guessed that 'adjustable' meant that I could control the amount of advance. Are you saying that it controls the 'rate' of advance instead of the amount?
Currently I'm running a stock HEI that the vaccuum advance is too large. Inorder for me to be at 32-34 degrees at 3K I have the base timing too low (retarded) which affects my low end takeoff until about 1500(also, I don't think that it's helping my mileage either.)
How do I limit the amount of vaccuum advance so that I can get proper timing at both ends of the spectrum?
Can it be done with a stock unit? Can I purchase a different vaccuum advance to accomplish this?
p.s. I'm sending another question to the seller asking this. I'll let you know what he replies. (Also - 'Made in China' is never a selling point for me)
