On my Cub, the TT.61RFS is leaking fuel from the high speed needle. The only thing I can think of is it's the rubber o ring. Any place I could get one other than ordering directly from the mfg?

thanks,,

You might have luck at a local hardware or home depot. I'm not sure if their o rings will be fuel resistant, some might.

A little trick I've used before is to cut a small piece of fuel tubing and slide it over the needle valve so it covers the threaded section completly. Might work for awhile until you can get an o ring. ENJOY !!! RED

If you know the size you want, then go to:

and type in o-ring. You're sure to find it there.

Part number 12845 as shown in the part list.

Where to find it I don't know.

I`m pretty sure the size you need is a 3mm outside diameter with a 2mm inside. I have a Magnum .52 4c thats giving me the same problem . The HS and LS needle uses the same o-ring.

Bruce is right , that is the part #

Cruz - I have a couple.
If you still are unable to find one - email me your address and I'll post you one.

frugal,,,,sent you a PM.

I have cut o-rings down and used super glue to splice the ends . Never tried it on one so small , think I`ll give it a shot .

I'm thinking teflon tape might help as well?? Maybe?

I have used teflon tape on a couple of SuperTigres and it worked well, but I can move the HS from side to side , and not sure whats up. Going to tear it down and see whats going on.

Try going to a transmission repair shop that does foriegn cars. I have gotten some pretty small metric O rings from them in the past and they will usely just give you a couple when you show them what you are useing them for.

Cruz - I have mailed a replcement ring today.

Thanks a lot. I'll let you know when it arrives.

Received the rubber o-ring in perfect shape. Thanks a whole bunch.

Heres my fix, worked better than when it was new.

Is that just plain ol' fuel tubing on there?

Looks like "plain ol' BLUE fuel tubing" to me.

Yep x-large. lol. Works great, takes a little fooling with.
