Re: homelite 55 fisher pierce
I had no difficulty shimming the cam followers on my Crosleys, F_R. I had to rotate the crank to get the "point" of the lobe pointing up and use two feeler guages to measure 1.) the desired clearance, and 2.) the size shim needed to get that clearance.
A compression check IDs what cylinder has a problem, a stuck valve can be eyeballed by pulling the cam cover and watching as you rotate the crank.
A standard valve job is, as you said, a full teardown so it amounts to a complete rebuild or at least an overhaul. However, on an engine that you can almost carry around tucked under your arm it is a lot less of a challenge than some might think.
As I said, the engine has to be totally disasembled to get the valves out. The real picnic is getting the clearance correct when you put it together. The clearance is set by changing shims inside the cam followers. Put it all together, measure the clearance, take it apart again (remove camshaft), change the shims, put it back together, measure again and find out it still isn't right, take the camshaft off again, etc, etc.
