Using a standard automotive tester, I'm seeing 60psi max after a couple of pulls. My Toro string trimmer shows 90psi. Not sure what to make of the result, since I don't have the repair manual/specs for the engine.
If the compression is wrong, what could have gone wrong? It seems unlikely the cylinder is scored, more likely something I did has caused the valve to not operate as intended and provide adequate compression.
With the sparkplug replaced and the EZ fire lever (choke?) engaged, I eventually get combustion smoke from the muffler after a few pulls and it occasionally sounds like it will almost fire but not quite.
It ran fine (years ago) but the pull-start mechanism failed. I replaced it (incorrectly) and found a sheared flywheel key (integral).
I got a new flywheel (with an integral key) and it is all back together, and I am trying to get it to start.
Supposedly the flywheel is the correct part but I suppose it could be wrong in terms of too many variables changing to isolate the issue (I do get spark on the spark tester and can see it).
