Carb drain leaking.
« on: July 20, 2018, 10:34:29 am »
The float bowl drain on one of my Khein carbs is leaking, despite the tapered screw being tight.
No doubt due to them being 30 years old, and me utilizing them several times lately to drain some fuel through to get the bike started.

I think I understand the mechanics. Could it be possible that the point is “bottoming out” before the taper seals? Anyone come across this?

I’m thinking the O ring shouldn’t play any part in the sealing process?

For tomorrow’s racing, I’m thinking of plugging the drain (sealed drain tube). Can’t see a problem with this.

I’ll have to dig deep into the road racer to pull the carbs (again). If the “seat” it damaged is it possible to repair?

Thanks for any comments/assistance.
