As Well as the 7D carb and pump, I also have the Standard 7M carb and a standard backplate for the 61V, I also have a second 61V but this one has done alot of work, I bought this one for the 7D and the Pump.

What I am gping to do is :> Run up the engine on my bench with a standard 7M carb if this is all good.

:>Fit the pump see if the engine is reliable with a pump feed

:>Then fit the 7D carb and see how this goes.


From these results decide what would be the most stable combo for the arrow.

I have also worked out by fitting a DUBROplastic Spinner I can move the engine forward by 1/4 of a inch this will give me the pump room I need

I will post results from my tests soon.
