Hi guys,

just a quick one, when stripping the carbs down the other week I found a small and I mean tiny O ring in the main jet, they had all miss shaped and were falling apart so whipped them out. On closer inspection I can't see an arm for them to sit on in the main jet and don't see a point in them as they are swimming in petrol so wouldn't make a seal (would they!).

I can't locate them anywhere and was wondering if they were supposed to be in there and how much it will hurt with them gone.

Any advice

It is a square ring not an o-ring. They are available as an original part 1AE-14227-00
