Gentlemen,
I recently started my Evinrude Sportwin 4421 for the first time, unfortunately it won’t stay running for very long. Looking back at the carburetor I found the up-stop for the poppet valve is deteriorated. It looks like ti’s allowing the poppet valve to travel upwards much further than originally intended. It’s going to need to be replaced, does it have to be replaced with cork or can a substitute be used? Would a piece of dowel rod suffice? If it has to be cork, could one be fabricated from a wine bottle cork? Any suggestions on how you could determine the length of a replacement?
Many Thanks,
Ray
