Trying to revive a 15yo Trade Tools 6KVA genset. I think engine is around 11hp. Many of the vacuum and fuel lines were split and have been replaced. There is what appears to be a small one way valve connected between the engine side of the carby and a diaphragm on the carby choke assembly. I have attached a couple of photos of it. Unfortunately this gizmo was already broken and whatever was supposed to be inside is long gone. Is there anything special about this valve? What can I use to replace it?
I don't really understand the purpose of this valve and the choke diaphragm. Can anyone explain how it is supposed to work?
While I'm at it I'd also like to know the function of a solenoid at the bottom of the carby. Is this a fuel shut off in case of low engine oil?
