Thanks for your interest. I think I may have found the root of the problem. I checked the timing marks on the crankshaft pulley. They are marked as 30 and 32 degrees. According to Wayne's book it should be 38 @ 6000 rpm. 6 degrees retarded by the looks of it. This is probably where the power is going. I also checked the part number on the distributor. It is 0231 184 004. Will check that that is the correct item too.
I think you're onto the source of the problem. I just tracked down a whole host of problems with my own car last year, and the solution: rebuild distributor. Putting a timing light on the distributor revealed spotty triggering of the spark - this wasn't apparent until the new one was in there, and was "spot-on" compared to the old one.

Also, be sure to check total advance. This is very important - if the weights in your distributor aren't advancing enough, you will rob yourself of power on the top end. I explain the procedure for timing and checking this in both the Engine Rebuild Book, and the 101 Projects Book...

Just from memory, 004 is the correct distributor. I think we sell Bosch factory rebuilt ones for $350 or somewhere in that range.
