I have a Kohler 301K engine with a Carter carburetor. The engine has always performed very well, but recently has been stalling out after running only a short time. I initially thought it was being starved for fuel. I cleaned and rebuilt the carburetor, replaced fuel filter, and replaced the fuel tank which had some corrosion. I even replaced the Carter carburetor with a new Walbro but I am still having the same issue. I am now suspecting the problem is electrical. What is the likely culprit? Coil? Condenser? Spark plug? Points? Other? Appreciate your input, Joe

I'm looking for help in troubleshooting a starting problem with my 520. I used it yesterday to mow my yard for about 1.5 hours and when finished I let it cool down before shutting it off. It sat for about 2 hours and I put fuel in it and drove it on the ramps to clean the deck and after rolling it off the ramps I hit the starter and the engine made a noise and tried starting. I tried several times after that and no pop at all so I did a compression test and the front cylinder was fine and the rear was poor so I immediately thought of the valve seat being loose wedging the valve open. This morning I took the head off and much to my delight I did not see the seat as I thought but the head bolts were not very tight so I understand the poor compression (see pictures). The piston goes back and forth so that seems fine so I'm not sure where to focus my attention next. I am new to the 520 world and I tried searching the forums to find a thread that might walk me through this to no avail. I'm going to hold off putting the head back on just in case someone says to check something else related. This machine is new to me and has been smooth running, no smoke, good power, and always started easily with very little choke so I'm very surprised at this. Any help would be appreciated.
