I worked on a Lawnboy silver duraforce last week that had a warped carb.Why did the carb warp?The ones I see with warped carb bodies are covered in gook so there is no way the heat can dissipate.You have to clean em up once in a while with engine degreaser and a tooth brush then spray down with brake parts cleaner.

It is possible a really hot engine (?300F) was doused with water somehow. Especially if the carb is aluminum alloy and locked down tight to a cast iron head ,both with different expansion rates. But it would seem you could carefully dress it down flat (unless you hit small passageways?) I'm winging it here.

its plastic carb on aluminum block Is it possible to mill the flanges down flat?:I will try that and let you know
