Re: The engine has developed a knock
If the rockers in question are Yella Terra shaft mounts, they require a little more attention to setup properly. You have to establish a proper wipe pattern by adding or subtracting shims and then establish the proper pushrod length using either an adjustable pushrod or dial indicator. Many of the problems reported with Yella Terras are the result of improper setup.
