I recently replaced head gasket on my 19 hp bs engine.. When inserting push rods I turned engine by hand to make sure rods were in groves. I obviously messed up timing when I did this. How do I get it back in time? thanks in advance. KLN
You can't change the timing just by chainging head gasket. About the only thing you can do is get the valve clearances out of adjustment. Make sure they are both .004-.006 with the piston 1/4 inch past top dead center on power stroke (both valves closed)
