I am doing a tune up on my 1956 15 HP Evinrude 15016. I noticed that the wick that is supposed to rub on the cam and lubricate the points is missing. The retainer is there but it looks like the wick has disintegrated over the last 50+ years to where it is not really there. Does anyone know if they are available, or if I really need it there? If so, what lube goes in the wick? Oil? Grease? What is the wick made of? What little is left looks like felt. Thanks, Rick
