Topic: '75 petcock oring?

[Dunk]

I went to rebuild the petcock on my K5 today using the 16952-341-671 petcock rebuild kit. It would occasionally weep a little and after recently rebuilding the carbs I figured a new sock filter would be prudent. The kit comes with a new nut, gasket for the nut between the petcock and tank, gasket between the sock filter assembly and petcock. It does not come with the oring that goes between the valve handle and petcock body, which is likely the one that was leaking externally since it's dried and cracked.

It looks like it would be a 1.5 x 19 as the OD of the handle is 19mm and the ID of the petcock is a slightly over 22mm. I'm guessing there may be some crush or squeeze of the oring when the face plate is tightened. The fiche only shows it as part of the "body set" 16951-341-671. Anyone know the size or Honda PN for this oring? I may try a 1.5 x 19 or 2 x 19 but I know how Honda loves to use odd sized orings. Worried one may be too small and the other too big.

The 19x2 was too big and the 19x1.5 seemed small (slightly loose on the OD). Tried to cram the 19x2 in and no way it'll fit and seal. Almost like the ID on the 19x2 was very slightly larger, tried two of them. I decided to put the 19x1.5 in and add fuel to see if it seals, then realized after I added fuel I had put the original oring back in. It doesn't weep at the moment, good enough for now.

Doesn't that hack you off? A lot of my repairs to all manner of items consists of " well it doesn't work, how much worse can I make it? "so pull it apart, put it back together and more often than not, fixed. Sometimes permanently, sometimes not, but at least I know how to pull it apart next time. At least you have a result and can worry about other things.
