Carb help.. (kinda long)

As some of you may know my engine was shaking really bad and heres what i found out on Thursday.

Well my spark plugs were wet and were black when we checked them.
The mechanic said this was a result of the carb being out of tune.
I left the car at his shop so he could fix the doughnut on the exhaust and adjust the carb.

When I came back on saturday he said he had adjusted the carb and that it would last for a while but would eventually screw up my plugs and the shaking would return because the carb is basically no good anymore and said either get a new one or rebuild it.

Anyway, the engine shakes whenever I turn it on then goes away after it is warmed up, until I come to a stop and it shakes a little. Also whenever I go from park to reverse or drive the engine shakes a little but then recovers.
Basically I am only in a little better shape than before.

The present carb was rebuilt only a year ago and is already giving me problems. So would you recomend getting a new carb or rebuilding it again?

Thanks in advance and sorry for the long post... I am really frustrated.

my guess is that you have too large a carb for the engine, and if thats the case, you will never get it to run right.

Well I have only had the car for about two years but it was my dads before and he has been running the same holley 2 valve ever since I can remember, without problems, until about 1997 when he stopped using it and it sat until 2001 when I started to drive. We got most of the kinks out(carb rebuild, new water pump, fuel pump,and other stuff) and it had been running great until recently.
