All right, anyone working for Dolmar listen up. The last two PS7900s I have gotten in have a pathetic excuse for a chain tensioner. The first one I sold was brought back by the customer because he couldn't tension the chain, and his complaint was legitimate. Upon investigation we discovered that the tensioner was changed to a coarser pitch worm and pinion. The pitch is so coarse that the slightest amount of load on the tensioning pin, and the tensioner locks right up. Brilliant! I never have had a problem with my older style chain tensioner. Anyone out there know what is going on?
