Try adding a rubber impeller kit to the impeller blades to increase the throwing distance.Both of my Troy-Bilts have been kinda okay (I work snowblowers really hard) but they both had pressure pins either break or fall out which affected moving the chute. I couldn't figure out an easy way to replace these particular pressure pins so I've been using cotter pins which buys a little time until they break. They don't throw as far as I would like but other than that they've been dependable for 10-12 years now, and I really do work them to death. The Craftman blowers I've owned were never quite up to the job. The two I had were both on the lower end of quality, IMO.
