This is Bob Book - Greg told me you might be looking for some engine help and I just want you to know we'd love to help you!! From the symptoms it sounds like you just need a quality hone and maybe a set of rings. We'll be happy to work with you any way you request - Please call if I can help, I'd be excited to help you any way I can!! My shop # is (815) 933-3330 or my cell (815) 347-1449.
