No, not the 49--I have several of those. This is a 6.5cc, front induction/rear exhaust with what looks to be a 4 or 5 mm. venturi with Super Tiger type needle valve located at the back of the venturi--no spraybar.
Just wondering if I could find any info on it--like all MVVS engines I have seen, it is very well finished/fitted.
