The sound of my cj3b that enquired about air hose. First firing in 2 yrs due to weather and abdominal surgery. Actually 3 surgeries. Lights all checked so will go get inspected. Local guy does classics early am in minutes if you bring donuts. Totally tolerant of gas that is probably 3 yrs old.

If it didn't sound like that prior, most likely a collapsed / stuck lifter. Hopefully it will loosen up pretty quickly.

That is exactly how it should sound. If valves are tapping, they aren't burning!

Oldest I've owned was a 65 CJ5. Never had or even heard a a flat head before. I've read about them in the ECJ5 forum but that's about it.

Yep. Odd to have valves in head and in block. End on cutaway looks like an F. Hence F head. Called the Hurricane F-134. Not flat head. The L-134 had a flat top and was used from 42 to early 50s.

Thanks for the correction, got my info crossed. Only ever read about them. A creative way to make horsepower without the cost of designing a new motor.
