Hey everyone I am new here and I really like this fourm so I think Ill stick around. Ok so I have this 87 briggs 11hp vertical shaft on a lawn chief mower. I had it running but it runs very badly and shoots puffs of gas out the carb on startup and at low idle. When the engine is running at high idle it seems to bog and governer hunt. I look down into the carb and I can see gas shooting out of the jets. I originaly thought it was a gunked up valve so I look off the head and cleaned both valves with the wire wheel and lapped. My valve clearance at 1/4 past TDC is .005 intake and .010 on exaust which is what its suppost to be. But the engine is still doing the same thing! The carb is perfect, I soaked it and cleaned it out real good with my compressor. It gets a nice deep blue spark and the flywheel key is in right. Does anyone know what my problem is. Help is very apperciated. P.S anyone else here and young as me haha!
