Starter rope is sold at home centers like Lowes and Homedepot. It is important to buy the same thickness of rope so that an ample amount will fit into rewind spool(starter rope is sold by size from 3.5 to 6.5) . Remove the starter cover /fan cover if the starter is riveted to fan cover (or just remove the pull rewind if bolted on). With cover removed, notice how the rope enters thru bushing and ties onto spool. Visualize in which direction the spool turns when you pull the rope. This is the direction that you will be winding the spool. Fish out the old rope and wind the spool in the direction mentioned above. The spool will get tighter as you wind. When the spool will not wind another turn, back-off one turn and align hole in spool to bushing on cover. Insert rope thru bushing into hole and tie knot (any knot that will not obstruct motor parts). At this point allow the rewind to take-in the rope to stop at handle. Test your work. The rope will break if you try to start the washer under load. Press trigger on wand to release pressure. Also the rope is stressed when the operator has a very long strong arm and pulls out the rope to bottom out at the knot. Good luck with your repair
Check your manual to see if it call for premium or regular. Premium has less energy per gallon and is designed for higher compression engines. What makes it "premium" is more anti-knock compounds - not better quality or performance. Sounds like a vapor lock problem that resolves as the engine cools. Regular gas may help with that.
Likely either the engine is flooded or low compression.
A simple go no go compression test is remove spark plug and press a thumb or finger firmly over the plug hole and crank engine. It should forcibly push your finger and make a loud PFFfft sound. No or little sound equals insufficient compression.
If the push rod was not bent, there was no reason to replace. If it was bent then I question how you set proper valve lash with new pushrod as the typical cause for a bent rod is a displaced valve guide.
If compression is OK then likely it's simply flooding and you have a carb float/inlet needle issue. Crank engine, remove plug and if it's saturated with fuel then it's flooded and a flooded engine will not fire, even with starter fluid.

Surging is usually caused by an air leak in the inlet manifold.
Remove and sharpen the blade. If the blade is sharp, it will slice though the grass with no resistance. Over time, the cutting edge gets blunted by stones, grass and soil. If that doesn't fix it, remove the carburetor, strip and clean all the jets. Make sure you count the turns and write down any pilot jet settings.
Check the fuel lines. My brother had one that wouldn't start because when the fuel line was forced on to the fitting, some rubber shaved off the inside of the tubing and blocked the fitting. Also inspect the fuel filter and fuel cutoff or check valves if these are present.
I haven't looked up your particular model, but some riding mowers have fuel cutoff interlock devices. Check those for proper operation.
