Mine used to get up to just under 185mph, but fell back to around 170mph after I changed spark plugs. I had been using Autolites, but switch to the recommended Bosch plugs. That was a bad idea. I reinstalled the Autolites and gapped them at .065 and managed to get back to top speeds of right at 185mph.
