Blocked up filler cap

Post by piper109 »

The tank cap used on R27, R60/2 etc breaths by allowing air into the small gaps just inside the cap edge I believe.

I have a cap that is completely blocked up but nothing is visible.

Does anyone know how to unblock this cap? By soaking it in something perhaps?

Thanks, Steve
