So i am rebuilding my K181 and i noticed the can weights have been rubbing on the intake tappet. Has anyone else run into this? I am getting ready to start reassembling the engine after getting it back from the machine shop. The cam weights are loose, not sure f they can be tightened up or not. Also the bottom of the cylinder is chipped out, from what i have read it will not hurt anything. I will try and attach some pictures. Thanks for any help.
