Martyn,


The MVVS radial mount uses the same crankcase bolt holes, so I would not discount the displayed mounting method.

However, the MVVS radial mount comes with bolts that are longer than then the original back-plate bolt that they replace.
For robustness, it is important that you obtain bolts that would engage the full length of the thread.

If you use the original bolts, only a portion of the thread would be engaged and it could be stripped out, if you are not careful when tightening, or even in a rough landing.


Rotating the carburettor slightly will not alter its behavior too much, unless airflow is adversely affected around the intake.
