The fuel line plug on my GT225 had eroded and was spilling out fuel preventing it from starting. I couldn't get it to hold enough fuel to start it. Since I've fixed the seal, the tractor won't start. It clicks when you turn the key to the on position, as expected but when trying to start it, it grinds. Any thoughts on if this is related to the fuel issue or if I just happen to be having another issue at the same time?
