In the accompanying drawings there is infFigure 1 an
engine induction system 10 having an intake manifold 12
on which the ñange 14 of the carbureter riser is adapted
to be seated and bolted. An adapter 16 is interposed
between the ñange 14 and the manifold 12, this adapter
having mounting ea'rs 18 and 20 through which the car
10 bureter mounting bolts are passed.
An annular groove `
22is formed inthe adapter 16 and is in registrywith the
bore of nipple 24. Inwardly opening ports 26 are regis
tered with the annular groove 22 and with the throat 28
of manifold 12.
