Hello, just bought an 8HP to replace my 6. But it seems just as fast. Therefore i checked the tag on the tail, and it seems to be there's another one under it. Therefore i thougt it would be an 6HP, but the cilinder says 8. Ive got this number of the cilinder: 8758472c3. The airintake of the carberatour says 44. Of my 6 says 40. Does anybody know what the size of the carb of an 8 should be?<br /><br />And has anybody got some tips?
