I have a mower that I let sit for about two years while I had a gardener. Now I'm trying to use it again and it won't start. I drained and changed the gas, cleaned the plug, checked the air filter. I sprayed the inside of the cylinder and the carburetor with gumout. When I pull the starter, the engine ignites the gumout and runs for a few seconds, then dies again. So I'm guessing that means it is getting a spark so it's a fuel clog issue?
Anyone have any advice? This is a Craftsman (Briggs & Stratton) standup mower that has really only been used a couple of dozen times over the years--it's just been sitting in the garage for awhile. I live in Los Angeles so it's fairly dry here, but it has sat through some very hot temperatures in the summer.
