Marc,

Sounds like you got a pretty good car for $500.

I would take a look at a few things to hone in on the problem.

Ignition system - Make sure you are getting good spark throughout the RPM range, could be cutting out (Distributor, Brain Box, plug wires, etc.)

Fuel system - Same thing, get the RPM's up, and see if your fuel pump is keeping up. Some Fiesta guys will actually mount the carb sideways to fix the fuel starvation [problem, which is a problem on Fiesta's. I am using the same carb you are, but strange enough, no starvation issues so far.

Adjust the valves - This is very simple. Get a haynes manual and follow the directions. I cannot remember the exact tollerances, so check the book.

I would look into the valves & Ignition system first. If you are loosing power on the high end, sounds like you may be gettign some valve float or something.

Give it a try and let me know how it turns out.

I am always willing to help out another Fiesta guy, so ask questions!!!!!!
