honda hru 197 will not fire?

Hi, new to the forum. was hoping someone could assist with a problem with my mower.



I have a honda hru 197 buffalo bull with a GC160 engine. i have replaced the magneto, carburettor, spark plug, oil, etc. I have plenty of spark. Compression is at 60PSI. Don't seem to have a low oil switch on this one.



I am baffled with this one? is compression too low to start this mower?



I refurbish small engines but can't solve this one?
