I have ordered a mallosi mhr reedblock .. it says 'The Malossi reed valve for Piaggio engines comes with stuffer!' what is the stuffer? and what do you have to do with it thanks! I need to fit it asap!!
It's a wedge shape bit of plastic with a round hole in the bottom. Only use it if the opening on your inlet manifold is round otherwise don't fit it.
The part you mean is on the left here right? If so then you look at the bottom of your inlet manifold and see which one it is. If it's square you leave it out and if it's round you fit it.
