My idle is at 500rpm if im reading it correctly...
you have the notch at 0 and then there is 3 notches between 0 and 1 and sameway between 1 and 2 and so forth. So each notch should be 250 increments. well my needle is right on notch number 2. which would tell me its 500 correct or no?
Where does all your idle needle stay at?
