I have a 22 HP Briggs & Stratton intek engine on my lawn tractor. I replaced the head gaskets (2 each) and the valve gaskets (2 each), and put everything back together and now the tractor doesn't start. I turn the key and it attempts to start, but it doesnt turn over.
Background - the tractor started popping real bad last fall. I parked it all winter and moved it to my garage to work on it this past weekend. While disassembling all the plastic covers, there was clearly some mice nesting so i cleaned it all out. I also cleaned out all the oil buildups on the fins and got the engine real clean on the outside. I assumed my engine blew the gaskets due to overheating, likely due to mice and that continued leaking oil out creating buildups. buildups = high heat = no bueno. Anyway, while i removed the valve covers, I noticed one of my push rods was bent (it was the bottom one made of steel, not aluminum, which I believe is the exhaust one). After I removed the heads (is that the correct name) that includes the two valves, i noticed that the exhaust valve associated with the bent rod would not move at all. After some penetrating oil, it freed up and I could push it open by hand. I bent the rod back straight and reinstalled everything. I replaced all four gaskets from above and attempted to start the engine. Engine would spin, but no turn over. I checked spark and I had spark. I could hear clicking at the solenoid under the carb, and I could smell gas as it attempted to start. I would hold the key open for 20-30 seconds with nothing.
I ordered a new carburetor/spark plugs and swapped those out as well. Put everything back together and still nothing. The engine spins, but it doesnt start. Now my starter is struggling after holding the key for over 15 seconds as it starts to whine at me.
I'm at a loss. I can hear deep bass gurgling/burping out of the hole near the air filter on top. One of the other posts mentioned that as well but there wasnt a solution. Someone said something about valve lashing?? I made no adjustments to my valves after i straightened out my rod. Maybe that is something i need to look at??
Otherwise I am at a loss and dont know what else to do. All the other videos I am watching are pointing at the fuel pump or the carb solenoid (both of those are good). After replacing the carb/plugs and holding the key in while the engine is spinning, the two exhaust pipes are getting warm, so I feel that the combustion is occurring. But its not turning over. Please help!! Thanks in advance!
