In the never ending search for a better way but in a simple fashion using what was available from days gone this little idea may help you keep your fuel lines and throttle cables safe and secure in a very sanitary way with very little expense.
For the most part the majority of Karters will use the tried and true cable tie, ziptie or whatever you want to call it to keep their throttle cable and fuel line held together and not flapping in the breeze which make perfectly good sense since both your throttle and fuel line end up at close to the same place on your carb.
Here is where this tip may be of benefit to you. The problem with a cable tie is that in order to keep the tie from sliding around and keeping your fuel line secured to your throttle cable you must draw the cable tie down to get some resistance but as you draw the cable tie down you are also collapsing your fuel line simply because of the inherant shape of the inside of the cable tie loop and the tension need to create some resistance.
The solution to this problem is to use a O-ring instead of a cable tie. Yep, just a simple rubber O-ring in any rubber type you have laying around or what can be found at any auto parts house or hardware store in the pluming section.
You will have to determine what inside diameter you need for your application
Here as a example of the O-ring set-up on my modern kart engine but it will work just as well on any engine or carb set-up.
This tip will work weather you are securing your throttle cable to your fuel line or if you are securing multiple fuel lines to each other for a dual carb set-up plus the O-rings can be slid easily to your desired position but stay in place quite nicely. The 'round' inner shape of the O-ring follows the contour of the fuel line better then the inner shape of a tie wrap preventing fuel line collapse thus the fuel line flow is not compromised.
See you at THE BIG ONE...R.E.A.R.
