My nephew has my 64 with a 230. He is concerned about that rumble or pop that an inline can make off throttle. I have read it is an over lean condition but have no idea what to do about it, if anything. I always liked the sound myself and passed it on to him with a old cherry bomb. Maybe a new style muffler? He is mostly concerned that it might harm the engine. What do I tell him? Thanks.
