when trying to set the ignition timing on my car, i have it set at 20 degrees and tighten the middle bolt on the cas. as soon as i touch the other 2 bolts it drops down to 10 or even 5 degrees. the onlt way i can keep it at 20 is to have only 1 bolt tight. sometimes 2. when tightening the cas isnt even moving though.

what the hell am i doing wrong?
