Default Yamaha 40hp No choke carbs

I bought three carbs for my 86 Yamaha 40hp engine. The carbs that came off the engine had choke butterflies. The three carbs I bought were from a newer engine and don't have any chokes. They did come with a small unit that apparently pumps fuel in behind the carbs instead of chokes. Any idea of where this went or how to plumb it into my engine?

Default Re: Yamaha 40hp No choke carbs

I'm not sure what year they are from. I bought them from Ebay last year and I'm just getting around to working on it (1001 daily car, truck, Harley, boat, etc., projects) I thought the guy had them advertised as 89 or 90 I'm not sure. I was hoping someone on here would have a three cylinder 40hp Yamaha with this type of carbs so they could tell me where the enrichner or whatever it is, is hooked up.
