Thanks Tom. I haven't checked the base tightness. Usually I notice it when I drive on the street. I'm probably due for some new gaskets under the carbs anyway. I'll give it a try. I have not physically gotten out to see if or where they are hanging up. It's usually idling soo high that if i were to put it into park or neutral...it would rev pretty high. What were the solenoids used for on the originals?
