I bought various size and thicknesses of fiber washers
at the hardware store that I’ve been using on carburetor
screws, etc.
The last HD-25 Johnson that I got running got about
four new washers on the carb. I’m begging to wonder
if they’re not meant for gasoline. I can’t seen to stop
fuel from dripping from these screws. I’ve re-tightened
them several times where you wouldn’t think they’d
go any tighter. Almost had a steady drip out of one
screw today as it sat on a saw horse. I was able to
tighten it again. Either the washers are turning
to mush or are permeable or something!Also, on the 54 Fleetwin I fixed up, I see the
shift pivot screw is weeping slightly, where I’ll have
a drop or two of gear lube on the floor each day.
Tried tapping the screw with a hammer and screw driver,
and was able to slightly tighten it more, but it’s
still weeping.Are some fiber washer "better" than others?
What have you been using successfully?Regarding removing the gear case shift pivot pin
to replace the washer…….
What’s the best "gear", F, N, R, to be in when
removing the pin? And would it be better to
have the outboard laying on it’s side to be
successful in getting the pin back in place?
I really don’t want to open the gear case
back up, as it’s just the pin leaking!Video of today’s adventure on the Fleetwin.
I think the bugs are out of it now, other
that the pivot pin leak!

May 13, 2017 at 11:06 pm #57663Have the gear shift in neutral, and yes lay on its side. Don’t touch the shifter and you should be fine. Sometimes you need to center with an awl, but usually it wont move.
Regarding packing washers. Just use the OEM ones. I have tried a gazillion different things and keep coming back. They work the best period.
May 14, 2017 at 1:55 am #57674Buc, The Fleetwin looks liken it ran well today! I agree with Chris P about the OEM packing washers. I have not yet found a viable substitute. The OEM ones work great.

May 14, 2017 at 2:13 am #57678I’m not referring to "packing washers" as on carburetor
hi or low speed needles. Just having trouble with
fiber washers leaking on the HD-25 carb, as
the four shown on this Ebay carb with the
red washers under the screws.
Is there a better grade, fuel proof fiber
washer than the hardware store variety?Chris, Thanks for the advice on the pivot pin!
Ben, I’m happy with the Fleetwin, wished
all of my motors ran that nice, lol.Prepare to be boarded!
May 14, 2017 at 3:02 am #57682OK, I understand now. I’m not sure what the red OMC sealing washers are made from. I have not had to replace any of them with anything but OEM yet (only on fixed jet OMC carbs).
Great to see amd to hear that motor running so well!

May 14, 2017 at 5:53 am #57691I’ve used hardware store washers with great success. You might want to make sure there’s no corrosion or damage to the casting or under the screw head which might cause a leak. A quick buffing with a wire wheel will remove any old sealer or remnants of the old washer making for a clean surface.
May 14, 2017 at 10:31 am #57694dont know if it dissolves but have you tried several layers of teflon tape on the threads first . the yellow teflon one is thicker and should fill he thread gaps well before the packing washers

May 14, 2017 at 1:16 pm #57698I’m usually pretty careful cleaning surfaces that need sealing,
using a dremmel with various brushed on the carbs.
Teflon tape would be hard to apply on those tiny
screws, but perhaps when I take it apart I’ll apply
some type of sealer on the threads and washers.
Tell mom, "Happy Mother’s Day" !Prepare to be boarded!
May 14, 2017 at 1:33 pm #57700Not only is the yellow thicker, it is actually intended to use where gasoline is involved, the white teflon tape will not hold up well.

I have used nylon washers when the fiber ones were unavailable. . . 😉
