Hi guys
Mercarb 2BBL 33049565 7Y03 fitted to a 1988 Mercruiser V6 4.3L
I originally posted a thread to ask if fuel dripping from my Carbs venturi's was ok. NHGUY talked about a Power Piston which in turn lead me to this missing part, to which I thank him, because I couldn't find it on my Carb, or in fact in the parts list in the Mercruiser Service Manual.
I posted a thread asking about the missing part (a Power Piston or Power Valve Actuator as achris calls it) to ask further questions and achris very kindly helped out to advise that it should be there. He also said that it was not a stock part and I may have to find an old carb from somewhere and use its bits. I've tried all the Mercruiser Service Centre's in the UK and some of them don't even know what this part is or does.
So here's my dilemma, its a $10 part which may cost me a new Carb which is about $6-700 depending on which Parts store you visit, or there are re-manufactured ones on Ebay for $300, new Air Horn's are not available seperately any more.
I've written to two US Carburettor shops who sell a Rochester Power Piston but they didn't know if it would fit mine, but there is a guy online called Mikes Carburettors in Rochester who says it is not the same and will not fit and he doesn't have one.
Since you guys are extremely resourceful and very helpful there might be just the one avenue which one of you knows about which I need to go down to find someone who has an old useless carb with this bit in it which is servicable.
Help?

Where is should be and a drawing of the part in the Carb
