I tested my Cline fuel regulator today for the first time on a Saito 1.50.
I found that the high speed needle valve became less sensitive (as stated in the instructions), but I have the impression the low speed mixture became more sensitive. Closing or opening the idle needle 1/8 turn gives me a difference between idling forever and dying from like 3000 or 4000 rpm.
My idle needle was not that sensitive before I have the impression.

Has anyone had similar experiences? The engine is still on the test stand and has about 1 gallon through it. This means it is still running on the rich side, but this should have nothing to do with the regulator.
