Intake manifold and spacer question  By  eman (Read 619 times)

I know my scooter has been worked on before I bought it. What should it have sealing the intake manifold and the spacer below it? The manifold itself has an O-ring which should seal it to the spacer. I see spacers with gaskets and some with O-rings in the spacer. What would be the best? Scooter started idling poorly and spraying a little choke cleaner near the base of the manifold changed the idle. The plastic spacer has a crack in it so it needs replacing.
