bucking under load

[aeidian]

89 2.9 5spd 4x4

Made a left turn out onto the highway and the truck died on me. I thought maybe I let the clutch out too fast and killed it, but it wouldn't start after. It just turned over and over. I had to hold the pedal to the floor before it would start to catch. Finally after about a minute of continuous turn over it caught but it barely ran. Felt like thetiming was off. Giving it more than a little gas tried to kill it, but it didn't idle right, just kinda clunked. After a few minutes of running it started to idle normal, probably burning the flood out that I did because it smellled rich. Now after driving it a bit it bucks while under load, accelerating. I can rev the idle up in neutral and its fine, its just under load, accelerating.

Ideas?

Bucks worse at the lower end, like 1st, 2nd, and 3rd. 4th and 5th only slightly.

Smoothes out the longer I drive it, just did a 30min drive from work to home and it was barely noticeable, but after I parked it for 10 mins and drove it again it bucked pretty bad. The first crank is a bit slow to turn over but after that its fine.
