hmmm.... when I messed up on my timing chain (believe me, I've done gobs of them and then did it wrong... LOL), it acted just like that. I mean it started and idled fine. However, it wouldn't pull or rev. I had the +/- 4* chain. I went dot to dot and accidentally lined up the dot on the crank key instead of the dot on the tooth key. It was slower than a 2.2 K-car with the A/C on. I mean it was bad. Not say'n this is your problem, but just say'n....
