Carb o rings

[Dom]

I'm trying to find somewhere in the UK that I can get the o ring that holds the needle jet in to the carb housing, would a neoprene o ring from ebay work if I knew the right size?

I think 1mm x 3.5mm ID viton will work.

Viton would be the right stuff, dimensions 1mm x 4mm (3.5mm may work)

I read @5twins saying he thought 1 x 3.5mm would fit but I can try the 3.5 to start

If 5twins said so, it must be right

Suzuki published the actual size in some of their parts diagrams but it's very odd .....

I've used the 1mm x 4mm size for many years but may try the slightly smaller 1mm x 3.5mm at some point. I've never even seen a 1.1mm diameter o-ring listed for sale anywhere. You can actually still buy the Suzuki one, if you don't mind paying that much for one o-ring.

I've ordered 5 @ 1 x 3.5mm for a whole £2.13 delivered, do you think they may be a bit loose?

 

[5twins]

No, I think they should be fine. They may be a bit difficult to install though. Even the 1 x 4 size takes some stretching to get it on.

Thanks @5twins , now to get the stubborn black build up off the butterfly edges.

 

[5twins]

Since they're brass, I gently hand polish them with Mothers or Blue Magic. It cleans them up nicely.

1 x 3.5mm was a nice tight fit, maybe a but too tight but they aren't dropping out any longer.
