we were off a tooth on the distro so i went to TDC. lifted up the distro. rotated it by one tooth back. re-set timing. NOW THE CAR SOUNDS LIKE CRAP and won't idle. Tried anything from 12-23 degrees.
i was at 17 degrees initial before the rotation and it was running smooth as a kitten at 950rpm. now at 17 degrees the idle is like 650 and it wants to die. i upped the idle screw a tad, but that is not a solution. if i rotate to some 23 degrees it seems to like that, but that is way too much. vacuum is at about 15 inches of mercury which says "hey ur timing is too advanced" but it likes more timing advance.
i pulled the rotor. brand new MSD Street Fire distro. springs look ok. weights sling in and out. vac advance i locked out at 5-8 degrees. i had it running 5000rpm WOTs testing timing on Monday just fine.
vaccum advance is unplugged. when i plug it in to ported, i get no advance which is good b/c it means i don't have the throttle plates open causing a vacuum when i added more rpms.
i am honestly 100% at a loss here. 17 degrees before I went back a tooth was 100% fine. now, it isnt. what the hell?
obviously when i rotated the distro i had to move the crank so it would rotate the oil pump tooth so the distro would drop. i am 100% sure the distro is all the way seated.
I checked the plug order 500 times. It is right.
All the vacuum ports are plugged so no vac leaks.
I am truly at a loss how the change of one tooth could screw this turd, but not surprised.
Could I have damaged #1 plug wire when I tightened down the air cleaner? It left a mark in the boot.
Before and after photos of where the rotor was and currently is located.
