O-Ring Part Number

I am rebuilding two carbs for a 40FSR and a 60FSR and am in need of a couple o-rings for the low speed needle.

Would you guys happen to know where I could find replacement o-rings for the carb?

Thanks,

Sawacs

My best luck has been to measure them in metric with 3 dimensions and look on Amazon. I have found difficult to find Orings there. Usually then have to wait for them to be shipped from Asia.

Measure the old ones and get new ones from Theoringstore.com. Replace with viton and they’ll last forever almost. For the cost of a factory OEM set of o-rings, you can get enough from TOS to rebuild the carb 5 times.
