everyone seems to say that the timing chain can't jump a tooth on the crank, but it seems to me like this is what happened, in order to get 19* the distributer needs to be advanced way too far, almost all the way. i have my 20 links and the pins are at 10 and 12, the sprockets were ziptied to the chain from the begining, and are still and 10 and 12. the car also drives like ****, hesitates then goes, bucks, has irregular revving, but it was running fine with dizzy advanced for like 2 months, then one day started misfiring. so i put in a spare i had, did plugs, wires, fuel filter, cap and rotor. runs better than before but still skips or misses sometimes. the only thing i can think of is the chain jumped a tooth on the crank which supposively isn't possible, although it looks to me like it can. anyone have any ideas?
