Last night I was trying to adjust the hi idle rpm on my M to be 20% over stock. I have been running a 3-4 yr old "magic" or hardware store spring and governor response has been good. I back out the hi idle limit screw and my rpm"s max out at about 1820 rpm with the screw not touching the stop. I removed older spring and compared it to a new spring that I have that looks exactly the same. New spring had noticably more tension so I installed it and it was good for right at 1900 rpm and that was it. Ive checked my external linkage and it is not binding anywhere. Any ideas on what to check next? It seeems these governors should yield more rpm yet mine is still lacking a bit to meet my maximum allowed at a tech inspection. What are you guys thoughts on this?
