Hey guys. I have a L100 that I replaced the valves on. I adjusted the valve lash but am getting a back fire through the carb and exhaust and the motor will not start. Both valves are opening properly and I believe I seated both valves correctly. Serial # is 31F7070129E1. It is a 17hp Briggs motor. I have tried many different valve adjustments from .004 to .006 on both the exhaust and intake valves. The motor turns but will not fire. I am getting a back fire through the carb and muffler. Before I replaced the valves I could get the motor to run but it had no power, that is the reason I replaced the valves. Now I cant get get the motor to run at all. Any ideas?
