Abstract: This invention relates to an anti-adjusting butterfly valve type carburetor, comprising a kind of high speed adjustment oil needle having eccentric hole and a kind of idle adjustment oil needle having eccentric hole, and it also correspondingly discloses a kind of specialized adjustment tool having eccentric convex platform for adjusting the high speed adjustment oil needle and the idle adjustment oil needle. The invention also discloses a kind of high speed adjustment oil needle having eccentric convex platform and a kind of idle adjustment oil needle having eccentric convex platform an it also correspondingly discloses a kind of specialized adjustment tool having eccentric hole for adjusting the high speed adjustment oil needle and the idle adjustment oil needle. Compared with the prior art, the invention has the following beneficial effects: Because the high speed adjustment oil needle and the idle speed adjustment oil needle have the anti-adjusting structure, thereby ensure that the customers can not be adjust the oil flow into the carburetor freely, and then ensure that the engine is always in optimal setting state.
