Pushrod measuring issue

More information for ya. I also have the 1.6 rocker arms and that is where the push rod length problem started. Harland Sharp has a clear photo on there web site that shows the adjuster screw in the rocker arm as it should be. I had the same problem as you and found that a new set of push rods that were only .064 shorter were perfect.

Although mine aren’t Harland Sharp rockers, I’ll have to take a peek at their website then. I got a big enough dial caliper and 5/16” ball to measure and I only got .022” shorter (effective length) than what Smith Bros made me and that’s not enough for a safe adjustment.
