I have a 1995 Johnson 200 with plastic carbs. I took it to the shop because, after I rebuild the carbs, the engine would idle normally then rev up high all by itself. I could never get it to idle properly. I took it to a boat mechanic and he said the carbs are warped. He didn't say the float bowl,but the carb housing itself from over- tighting the bolts. How can I correct this problem without buying new carbs? I read somewhere about glass plate and emery cloth? What is the glass plate for?
