Feck sake…. Me and carbs.

Blowing out No.2, O-Ring on the table under the pic, flew up out of “somewhere”.

All jets etc were out at the time, (loosly, put back in for pic)

No idea where it came from.

Then…. found two “washers” in the bag of bits. in pic insert,

no idea where these come from either, (seem to be suitable to go under the circlip of the needle, but there’s two.

Checked three other carbs, nothing similar in any of them.

Any ideas – ‘Keihen 86 GPZ
