I have a Murray 17hp b&s 425007x92a
This mower runs pretty well great, other than the occasional misfire that occurs, and not being able to run it under 25% throttle, or else it backfires and stalls out.
I thought I'd take a look under the valve cover, and honestly, I dont know what to look for, or what I'm doing, as I'm new to working on these small motors, but the valve on top, the metal piece that transfers energy from the valve spring, to the rod feels a little loose? Compared to the one on the bottom. Is that normal to have some play? Does that mean the valve is possibly bent? And is it a huge job to replace a bent valve?
Thanks in advance!
