Bogged down While In Gear And Sputtered During Acceleration

Hate to say it, but this sounds like it is running just like my car was when I installed the timing chain a tooth off.

When I fired the motor up for the first time it started great, ran at 2000rpm for 20-30 min, started up again after letting it cool, but would bog and die as soon as I put it in gear. I was able to 2 foot it to drive it around the neighborhood a few blocks but it ran bad. As soon as I pulled in the garage and put it in park it would idle and rev like there was no problem at all.
I checked everything 10 times before I finally bit the bullet and pulled the front cover and saw I was a tooth off on the timing chain.

Even with the chain a tooth off I was able to set the timing at idle and at 3000rpm, and the timing did not move at all after I reinstalled the chain
