Greetings,

First, I'm an avid user of this site, great information.

OK, while searching around for help with the notorious bucking/hesitation problem I found the thread on secondaries being stuck open. While checking the secondaries I noticed mine do open at around 3700RPM but it seems they just open momentarily, The linkage moves as if they are opening then moves back to the original (less than 3700rpm)position. Could this be a bad IMRC (I think thats what it is)? or is that how they work? If this is faulty could that cause low rpm hesitation? Thanks for any help.
