Hi, does anyone know what the small plastic needle valve, that is in the petcock vacuum hose, is for?
I have attached a photo of it.
I am having trouble with my Firestorm losing power in the 2000 - 3000 RPM range.
Petcock vacuum line valve
Re: Petcock vacuum line valve
That's not standard. It's a flow adjuster from an aquarium. I suppose the po may have used it to attach a carb balancer- see if there's another one fitted to the front cylinder.
As long as it isn't fully closed it shouldn't be causing your problem, but it's easy to check, just replace the valve with a straight connector.

It's not falling off, it's an upgrade opportunity.

Thanks for that. I will remove and carry on finding the fault.
