I am new to the forum. Saturday, I was using my Gravely 546 to push a little dirt. It was running great as always. After about 10 minutes it just shut down like turning off the key. At first it would start and idle but would die when I gave it the least bit of fuel. It has fuel and it has fire. I am not a master mechanic but have some knowledge. Would anyone have any suggestions where I might start? Thanks in advance.
