new dizzy adjustment problems

ok 1990 4.2yj just did weber 32/36 ,team rush & nutter & got a cardone pre smog dizzy. ever since new dizzy im getting a rattle-detonation when i give small revs only happens with no load. and also pretty much goes away when i unplug vacuum from dizzy. so i checked the adjustment on vac canister & it was tight all the way clockwise. so hrabed my allen key and turned it back. ok not enough. so went to put allen key back in canister & it no longer fits. ive tried every size. ive been at this all night. it fit fine the first time. what the hell could have happened. im stumped. with a small allen key i canfeel it go in that extra bit. but next size up dont. but it did before. please any help would be great. i dont want to destroy my engine with this knocking /pinging sound. thanks..

ive even tried my friends. mine fit fine. nice and snug. then i went to go adjust it again and no matter what it wont fit. i know how stupid this sounds. i was thinking maybe the screw fell out. is that possable?? i have it turned out (counter clockwise) about 7-8 i think.

Hmm, good question - I never though of that but never had the problem
Im not really sure - never had to move it more than a turn or three
Hopefully someone with more knowledge will chime in
Those diaphragms arent servicable either
