Re: CB350 Squeaking Valve?
GOT IT!
This was the key:
The noise not happening when it the spark plug was in, and not happening when the crank was turned were important clues too
I depressed the valve manually and that didn't come up with anything but when I took the carb off and put my hand...
Re: CB350 Squeaking Valve?
The oil breather was unblocked when it started squeaking, it is currently blocked as I was tracking down the noise.
As far as I can tell, oil journals are not blocked. The cam holder oil passage was not blocked and the inspection port on the left side squirts oil...
Re: CB350 Squeaking Valve?
I did not check that. They appeared to have been tested when the head had been rebuilt prior to me getting the engine as they were dyed and I didn't verify. Compression is good in both cylinders however.

:) assuming I'm an ass... Anyway, I though I was too but I'm not 100% sure. Books say to install camshaft with the mark up. So that's what I've been trying.
Having done this on several bikes that were not cb350s I am feeling chagrinned.
Tried all the things and recommendations so far to no avail. A friend suggested rotating the cam shaft so all the lobes are down to facilitate installation so ill try that next.
Thanks for the replies all!
The roller tensioner arm is installed, the spring loaded part is not installed.
I am following the directions in the Clymer manual I have. Are the installation instructions different between them?
I'll try the tricks you folks suggested sometime this weekend...
