I have a Briggs 14.5hp riding lawn mower that when you try to start the flywheel won't turn or will make a slow turn and pause then another slow turn and stop. I cleaned the ground cables, replaced the battery, carb, and spark plug. Trying to jump across the solenoid doesn't work either so its not that. I was told that maybe the coil cold have vibrated too close and may need to be moved out a little? Also I have noticed that gas came out of the oil fill tube when I took it off. I checked the float in the carb and it seems to be fine. Any suggestions would be appreciated.
Do the valves need to be set is so how?
