Hello,
Just a real quick question, I am pretty sure that I have my answer but I wanted to check here first. I have a 1982 Merc. 120 (2.5L) with a Pre-Alha outdrive, and when coming to a slowdown after running with skiiers and tubers the motor sound like a teapot coming to a boil. It is like it is popping off steam, although I can see none, I hear it coming from around the carb/exhaust manifold area if I let it idle for about a minute it continuously goes UP in pitch, like something is being squeezed shut until it eventually goes away, until I bring it back up to speed and slow back down. It is ONLY when I slow back down and the engine revs down to idle speed. What is this? Any ideas?
