I hope yours works better than mine! Purchased middle of last year and the engine barely ran above a tick over. Anything resembling long grass and it stalled. I contacted Qualcast and in fairness they got back to me very quickly. The problem is that the only way to adjust the running speed of the engine is to remove the air filter and bend a piece of metal connect to a spring until you are happy with the engine speed! Not the best of solutions I think you will agree.
It's impossible to do the job with the engine running so it's a case of bend metal lug, start engine, bend metal lug, start engine, bend..... until you're happy. That doesn't guarantee that it will actually be OK when you start mowing. So it could be a case of off with the air filter again, bend......... Stupid design
