Thank you, I had the original assembly but some how its gone now. That the reason for my question. Should I fork out the big money and get the original or go with after market. According to the diagrams I found I think the original had some sensor in it and it also had a couple hoses. Can I get rid of the hose going into the porter breather ? I think it also had a vacuum hose going to the carburetor what about that one ? Sorry not a mechanic learning as I go
