AS MANY OF YOU KNOW, OVER THE WINTER I REPLACED THE ROD AND MAIN BEARINGS IN THIS ENGINE. WHEN I GOT THE CALL FROM THE OWNER, I WAS SICK. HE SAID "YOU JUST HAD THIS ENGINE APART AND PUT RODS AND MAINS IN IT. NOW ITS KNOCKING!" WHAT MISTAKE COULD I HAVE MADE? I DOUBLE CHECKED EVERYTHING I HAD APART. I THOUGHT IT WAS ALL GOOD. MAYBE I WAS WRONG. REGARDLESS OF WHAT I DID WRONG, I WILL MAKE IT RIGHT.
