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.
