I recently posted messages looking for a recommendation for my next ground saw. I have a ms200 for climbing and a 272xp for a ground saw. Recently, I had to bring the 272 into a mechanic due to a carburation problem I couldn't figure out. He pressure tested the carb and said that under the high speed adjustment screw there was a leak. He described brass and rubber components that couldn't be purchased so I needed a new carb. 4 days now and no carb from Husky yet. Anyway, several guys on this site were pushing the Dolmar 7900 when I asked about a possible new stihl460 or husky 372xp. I would like to confirm what I got out of the many helpful postings on this site. Will my bars for my 272xp fit the 7900? Are there any down sides to the 7900?
