Son Nick was driving the lark a few weeks age when he reported a big loss of power. Investigation reveals- sure enough two cylinders weren't hitting. New plugs no help, and we were getting spark on all 6
Compression check- cylinders 4 and 5 had zero pressure. Praying for a blown head gasket, we pulled the head. Prayers answered - a gap between 4 and 5 cylinders.
Took the head to the local guru for resurfacing and new valve seals. Cleaned all the carbon out + ordered new gaskets
We put it all together over the course of 3or 4 days, and this afternoon, we hit the key.
Fired the first time and purred like a kitten. I set the valves at .027 and got zero valve noise.
This is the first time I have been inside a OHV6 engine. I like it - simple and strong and well engineered (for 44 years old engineering)
Very nice father + son experience.
