OK, I have another question. I got the kit, and the parts are in this photo:
The big problem is the packing for the idle needle. Here is a part diagram to refer to. It’s from this site:
http://www.marineengine.com/parts/johnson-evinrude-parts.php?year=1963&hp=40&model=RD-25&manufacturer=Johnson§ion=Carburetor+Group
So, here are the problems.
First, parts 36 and 47 were just an ungodly mess of decayed RUBBER and plastic, but there are no rubber washers that could match part 36 in the carb kit. Only cork ones. But they look the right size. Should they be cork or rubber? Part 47 (two of them) are plastic as I would have expected.
Second, at the above link, in the bill of parts, it says that two of the 36 washers are required. I can’t tell how many (rubber) washers I dug out because it was just a mess. The diagram just indicates the number 36 once, and isn’t clear how many there are from the picture. Should I stack two 36 washers up together? Is that how it works?
Third, how is the idle needle assembly properly assembled? There is the aluminum bushing, threaded in the inside (part 41) and then the packing washers (36 and 47) and then the 46 nut to tension the packing washers. Do I stack all this up on the needle and then put it in the carb body? Or put the washers in first and try to thread in the needle? Most importantly, how hard do I tighten 46? Just until there is enough tension for the idle needle to be adjusted without the bushing (41) turning in the hole?
Thank you so much. I have worked on a number of small engine carbs but have never encountered a needle packed like this.
You guys are awesome.
