Rough Running 2 Liter, Is it just the cam? Options

[newdeal2]

I have finally had time to re adjust the valves after a test drive gave me the quivers. The car ran too "choppy" in the mid range under load so I figured the .004 on the exhaust valves were causing the problem. I re adjusted to the "safe" clearances of .006 intake and .008 exhaust.

Now it runs better but here are my concerns: The car runs like crap if I don't let it warm up to a decent temp...say 5-10 min's. Then it runs pretty strong. If I crank it up and just drive it's pretty choppy on the low end and get's up and pulls in the higher rpm range.

As you all may know I have euro pistons, Raby designed Webcam [73 grind] for stock D jet and that's about it. I have done timing, checked plug and point gaps [tried different variations], check all hoses [both systems]. Compression is pretty good [130-145 and still under 100 miles on the rebuild].

So...if it needs a good warm up, runs choppy in the low rpm range but grunts above the 2,000 range is it just the fact that I have a hotter cam than stock and it's just the nature of the beast?

Feel free to analize this!
