RB,


The new carburettor also has the same part number (#3216) and the same choke size (7 mm), but is a completely redesigned unit.

If the plane that you intend to use this engine in is a fast sport model, intended to fly primarily at either full power, or idle, you will have a sufficiently good performance and transition.

If your model will need to use frequent part throttle, it could load up the engine, since the mid-range fuel settings will be too rich. So for 3-D and the like you may want to either upgrade, or replace this carburettor.

This photo shows the new style carburettor (#3219 8 mm) in an MVVS .49.
