1957 evinrude big twin 35 correct packing

[eolsen]

Can anyone tell me what the correct packing sequence is for the high and low speed needles on the carb?

Not sure what you mean? I put a couple in the low, and 3 or 4 in the high. Snug up a little. Seat the needles, back the low out 1.5 turns, the high 3/4 of a turn. TIghten packing nuts. THen fine tune on the water.

If you have the thin plastic washers for backing up the soft packings, they go between the packings and the packing nut. They keep the nut from mooshing the packings so badly.

ok, so......2 in the low speed, 3 or 4 in the high speed. Thin plastic washers or no? Is this a preference thing or a specific thing? I've researched this extensively on the internet and I have heard about 20 different responses.

They come in the kit, so if you buy the kit, for sure use them. As Frank states, they keep the packing in a better state. If you don't have any around, don't fret, will work just fine without them, but could be a bit messier next time the carb is overhauled picking the old packing out.

They go in last, before you install the packing nut. 1 per hole.

have yet another response -- I use a couple of washers on each of the needles. It's kind of an elegant system (the needles). Have to make sure the low speed needle in particular is securely seated, but without breaking it (it's brass). Your 35 has addit parts too (springs, I think, unless that's the '58 -- not sure). You might practice seating the l.s. needle with the expansion fitting off on the top, if the carb is still apart -- get a chance to see how it works, and get the feel of seating it.

The larger diameter hollow jam nut "jams" the washers, and in doing so pinches the needle in place too.

good idea to look at a parts blow up, if you haven't already.

edit. cork washers are the ones that seal -- hard washers go between the cork washers and jam nut, if used, as described above. (Cork washers are the traditional ones -- softer than the plastic ones.)
