Thanks vccomm

.. not sure what the cause is yet, but the previous owner said he was using it then it just died, then couldn't get it to run again.
Haven't done much testing yet, was planning on getting a reference diagram 1st so I know what I'm looking at.
I did a compression test (never done one before.. so got to use my newish compression tester :)) .. got a reading of 55psi .. not sure if that's good/bad.. what is considered good/bad for a 4 stroke mowers compression ?
Going to take the carb apart soon, inspect and give it a good clean.
