Technically this isn't my very first engine crank (261 cu in - inline six) since I had to get the magneto and TDC aligned. This engine was rebuilt over a decade ago and only started to keep the cylinders oiled and never up to any temp. I was concerned about it even being able to start, but in the end, this was a success.
I now think I hear a valve tap. What is the lash or clearance that I should find on the rockers/valves?
