Local repair shop on vacation in peak mowing season? You must live in Colorado or Canada. Around here, you can't even pull into the parking lot to get a mower looked at. Our mower shops are busy.

There are two top dead center conditions on a four stroke engine. You could of set the valves on the wrong stroke.All four valves were set to .005 when the pushrods were recently replaced. Upon rechecking all four are still at .005.
thx
That 1/4" deal is to get past the compression relief.I can't recall exactly why the recommendation is to move the piston 1/4" past TDC,
I use the OVOOVC method with no comebacks or trouble.
One Valve Open, One Valve Closed, adjust the valve that is closed.
Agree on this. OP is trying to fix the problem overlooking what might of caused it to begin with. Need conformation on are the cooling fins and block CLEAN. As in a shiny new engine look down to bare aluminum. Pictures of everything assist us in helping you.While this can be operator error like running then engine at lower speeds than WFO or failing to clean the cooling fins
Agree with sgkent. Take the battery to an auto parts shop. Have the battery load tested for free.
Agree with Scrubcadet10. Need to do voltage drop testing on the entire + and - sides of the battery, while CRANKING engine. Also make sure the ground strap is a stellar fella'. Check every cable and connection on the + and - sides. Polish every connection while you are there. Little dielectric grease is your friend here. Star grounding washers should be added.
Do you power wash this after mowing? If so that is another topic as what not to do.
Reset the lash to .006 using ovoovc method.
The engine now starts repeatedly without hesitation!
There were mice nests and caked on debris under the cover when these problems began. I cleaned it out then but I cleaned it all again more thoroughly getting between all the vanes with a plastic brush. I’ll add engine inspection and cleaning to my regular maintenance routine.
many thanks to all for your contributions in helping solve these issues!

Dirty cooling fins is what caused this to happen. Keep the fins clean and the oil on the full mark. Easy right?
