Sorry for a really dumb question, but I really don't want to break anything. I need to change the air filter on my 230, but after I snap off the two clips, the air filter cover really doesn't move very much. Do I disconnect the hose that leads to the cover? If so, does it matter which side of the hose I disconnect? The three tabs that hold the cover on the back side seem to hold it very tight. Once the hose is off, do I just pull the cover straight forward? Thanks! I rebuild old farm tractor engines for a hobby, but this little MB is a little more fragile and less forgiving of brute force. Most tractor parts respond well to a hammer. I have searched the forum, but I guess most folks don't find this to be much of a problem.
