that is a great question, really.  I have been seeing little plastic clips.....at the hospital lol and Ebay that you can get I different colours aswell. I was very hesitant to do this> but it is my bike and hopefully allways will be. Secondly a Carb shouldn't leak fuel unless it needs new rubber seals etc.
Thirdly I have my Diploma for Engine Mechanics however im new at all this still.  Seems to me I will be OK right? I don't plan on wearing any fire protection so if anyone has an issue however situational/theoretical. I am all ears......
The hardest part now is deciding w way to mount it that is pleasing to the eye.
