Hi,

I have a 3W75iUS which I need some advice for.
The engine at the moment has a brass tube soldered to the diaphragm cover and a piece of Tygon tube going into the fuz. I have now bought a velocity stack for the engine aswell as an airfilter to quieten induction raw as the carb is poking out of the cowel. Do I have to take the pipe from the diaphragm cover to the velocity stack now or do I leave it vented to the fuz. The velocity stack is the 3W one but does not have a nipple on it. I think I need to so that the pressure on the diaphragm is the same as the pressure in the inlet to the carb.

Any advice would be appreciated.

Cheers
Stuart.
