Mine shook really bad, but it had a miss when reved. Here is the video I took with my dad starting it. when the camera shakes it was because I was leaning up against the hood brace.
The issue ended up being I had some wires opposite on the distributor of what they should have been. Does it sound similar?
*Edit: Yetti suggested the same issue while I was making my post Ha!
The distributor issue, I ended up setting it up one prong over. give the distributor a twist away from the housing untill all the cap prongs are about in line where they used to be, and move all the wires back over the other way one prong at a time. (I think thats how I did it) I have all the room in the world to adjust things now.
** edit edit: I also remembered it being a real biotch to get running, and yes, it died alot and very easily.
I'd re-check your fireing order.
