So you did not have to mod the carb at all? just the airfilter box?I have seen some knock off carbs with a airfilter box with it wonder if a carb and airfilter box for an 021 /ms211 would bolt up? i had my ms 170 and my 021 out today the 170 is very boggy in comparison....... sorry to dredge an old thread up .... thought i would use the search function before i posted.... I dont want to tear apart a new carb and jb weld it if i do not have to.....I have read many of the threads on the 215 walbro carbs and how they had to be modded is why i ask.... thanks .
