So was the Lash off the first go round? Sounds like it.

Best deal to verify and control accuracy of valve lash is from Precision Measurement Supply in San Antonio. Little valve gapper with dial indicator. Amazing how far off the "feeler" gauge method can be.

What is a P&G ? We thought that was a tool for checking engine displacement .

Yup , That's the Honda method , Honda wrote a SAE paper on that way of lashing valves years ago , documenting the benefits .
Many of us old farts set our valves that way before we ever saw a Honda.

Yep, I have an old antique P&G from back in the day, but they haven't been made for decades. :D



That is why I listed the piece from Precision Measurement Supply in San Antonio.....sure beats the heck out of feeler gauges. We ran a test a long time ago with a setup to see who got the correct lash and many name engine builders were all over the map when the setting was measured with a dial indicator.....jus' sayin'.
