Hello Everyone,
I am new here and looking for guidance/suggestion with a problem that has been bugging me all summer. Last fall, I bought a used Husqvarna with a 21HP Briggs Vtwin OHV. The mower worked fine but was leaking oil. I changed the sump gasket but I noticed that it was still leaking oil and burning it on the exhaust. Seeing spring coming fast I decided to change the head gasket that I thought as the culprit. Apart for the oil leak, my mower ran just fine before the head gasket removal except maybe for a slow crank when starting the engine. My valves and rods seem ok, no bend or unusual wear. I used the "screwdriver in the spark plug hole" technique to find my dead center and reassemble valves and I adjusted them according to specs (on the bright side, the engine cranks much better than before) but the engine did not start. I noticed a lot of gas being pushed out of the exhaust each time I cranked. I thought I smelled gas in the oil so I changed it completely and started all over again. Same thing, gas in the exhaust and ultimately in the oil. I took my carburetor out and cleaned it out, the float was working fine and the needle was not the problem. I checked my spark plug and electricity was passing by, I checked the air filter\, I checked the fuel pump, all checked out. I used some starting fluid to try to get a combustion but nothing. Any suggestion help would be much appreciated. I had a working mower all winter which I tried to getting in shape for the summer. As a result, I've been mowing 1 acre with my push mower for the past 3 months :laughing:.
Thanks
