air leak on the carburetor neck,can I seal it?

Hi guys, I am pretty sure I have found a leak around the carburetor neck on my super tiger .61, my question is can I seal it up, or put a fine bead of silicone on the neck and then place it back in and tighten it up again? my worry is that maybe the heat or the fuel will break down the silicone and allow it to enter the motor. if you have any suggestions, I would be glad to hear them,, thanks,,,Joey,,,,,,

Carb leak

Hi Joey:

Why not just replace the "O" ring around the carb?

I think if I'm not mistaken you can order the part. If you need the Super Tigre part number, it is 22020562 for the GS61.

You can get them from your local hardware or auto store too.

hi temp sealant at Cdn Tire. I think its the "red" tube (not blue).

Lotso people with GMS' use it just for that purpose (to seal the carb).

I had a broken O-ring on my OS engine's carb neck like you, and replaced it with an O-ring from Canadian Tire. Works great, it's not quite the exact same size (a little thicker), but didn't have a problem this season using it.

Best part: OS Engine sells their O-Ring at about three dollars. Canadian Tire sells their O-Rings at 15 cents each.
