7.5 mercury is not idling at all. i can get it to start but can not accelerate or deccelerate. i have tried messing with the idle adjust screws and they seem to be having no effect either way. It has great spark, and good compression. If i give it gas or lower the throttle it dies. I'm out of ideas here. On a side note, there is a rather large screw on the lower end with the word "flush" right above it. I don't know what this is for, but since it apparently has been removed several times i decided to take it out and see if anything came out of the hole while it was not running. only a tiny amount of water came out and i can see a bunch of white gritty stuff that looks kind of like large peices of sand. Just wondering what this could be, and if there is anything i should do about it. Any help would be appreciated.
