What size o-rings for Kyosho GX21 carb?

[Johan Z28]

Hi!

I just bought a old Kyosho Mad Force with a GX21 engine that had been sitting for years. Could not get it to run that good and found that the o-rings in the carb are hard and brittle.
The maintainance kit is no longer produced so have to buy o-ring separately.
Does anyone know what size o-rings are needed?

Yes. It's those little o-ring would like to know the size of. Worse case I have bye the whole kit. Would actually cost almost the same as the rc car
