I would strongly advise against using a Chinese “rebuild” kit.

July 13, 2020 at 10:05 am #208478very convincing….I just did none a week ago…:-( so the inlet needle fitting threads don’t fit,, the gasket melts

July 13, 2020 at 12:18 pm #208486I’ve installed a few of the offshore carb kits but haven’t checked the bowl gaskets yet. Gulp! Maybe I’ll get lucky by always using non ethanol fuel. The float valve seat has the correct thread pitch but they aren’t cut deep enough and need to be chased.
July 13, 2020 at 12:24 pm #208487I always wondered what that big fat o-ring was for, too. Maybe it was for a carb that was even before MY ancient time? Looking at the picture, I can’t now help but wonder if it is the same as a shift shaft o-ring……not that it would be it’s purpose in a carb kit….
Good question…Does anyone know what that round rubber donut gasket is for, I have a collection of them also… That Sierra kit must be very inexpensive, not much to it… I do my best to avoid Chinese stuff at all costs, but it is near impossible to avoid….Don’t get me started….
Drifter, That’s incredible! Thanks for posting. With some parts, when I’ve had to, I’ve resorted to using used OMC parts rather than new Chinese parts. I do love their spare ribs, just not their outboard parts.
As for the big fat donut o-ring/gasket…I think I remember a fat o-ring like that in the ’53 Johnson 10 horse carb. (I think some may have had an actual seal instead). I know the kit doesn’t apply to that year, but I checked my parts manual for the number (part 72 – 302832) then searched to find a picture of it, and it looks like it could be the same as in the kit. Maybe someone who’s got a QD-14 carb apart and that carb kit could verify it. Might be in the earlier QDs also.

I run ethanol gasoline. Bad news.July 13, 2020 at 1:14 pm #208499Keith,
