Re: 40hp Johnson 1963 Carb Question

Those cork looking washers are the packing washers. Lots of different looks for them, they all do the same thing though.

Put the bushing in first, if it fell out.

Then they say to put a plastic 47 in, then I put 2 or 3 of the packing washers in, 2 should be fine, then another plastic 47. The 47 washers keep the packing washers from getting destroyed, like you found. You can drop them in the carb in order, then put the packing nut in a turn, then start threading in the needle until it seats. You may need to tighten the packing nut a little, to keep the bushing from free spinning in the hole, while you seat the needle. Once seated, back it out 1.5 turns, then you can fine tune it on the water. Then tighten down the packing nut more.

Or thread the needle in, slide the gaskets in over the needle, then the packing nut over it all. There are many ways here to do it really, just personal preference.

You want the packing nut tight enough so that the needle doesn’t vibrate around loose, but not so tight that you cannot turn the needle at all.
