Rock stuck in vane and wore through center section .
This is a pet peeve of mine .
My point of this post is to price out parts on small engine to determine whether to repair or replace . For some reason small engine parts are priced in such a way that it is sometimes CHEAPER to throw it away than to repair . It's our job to repair and save money and I really hate to throw something out that could have been fixed but that's how this industry is at times . To my shocking surprise the parts alone to repair this one = to a new replacement . Next time I'll be shopping for a new replacement and putting the 4 hp Honda perfectly good engine on the shelf .
