When I was much younger, working alone, no air and no impact, I put the socket on the bolt, put the 1/2 drive long flex handle on the socket, pushed it down against the frame on the right side, (your left as you hang over the radiator), then touch the starter. I remove the washers from the bolt, then have the puller press against the bolt. Use a thread chaser to clean the two bolt holes in the casting, then pull away.
