👨🔧 - The trick in Michel (the corner of the expert)

* "Hi the nozzlers! In karting, especially on the engines Rotax with the CARBU DELL'ORTO VHSB 34, the air circuit and overflow is ultra-important. If your air hoses close up, pinched or grope with dirty essence, the tank of your carburetor will put pressure or depression. Result: the high speed ratatouille engine, regulates, or choking completely without you understanding why !

My essential mechanical trick for your silicone hoses of 5.3x3.2 mm: bevel cut and evacuation loop !

First rule: when you cut off your hose lengths to connect them to the two lateral locking chimneys of the dell'orto, cut the free end (the one hanging down) bevel (whistle) Using a sharp cutter. If the hose drops straight in your recovery box and it comes to appear flat against the bottom of the jar, the air will no longer circulate and your carbur will mess. The bias cut guarantees that the air always goes.

Second small tip: Take off your overflow hoses by forming a pretty soft loop before sending them to your recovery bottle. This loop serves as a "drop trap" and prevents vibrations from riding directly into the tank. And then between us, a motor with clean silicone hoses well clean and aligned, it shows immediately to competitors that the mechanic is a perfectionist! "*

❓ - FAQ SEO (Frequently Asked Questions)

Q: Can we use this hose of Ø 5.3 x 3.2 mm for the main fuel supply from the carburetor tank ?

A: No, it's not recommended. The interior diameter of 3.2 mm is perfect for the air-conditioning and overflow circuits of dell'orto carburetors. For main fuel supply (from the pump tank, then the carburetor needle pump), the required flow requires a hose of an upper inner diameter (usually Ø 5 mm or 6 mm inside). Use this article exclusively for breathes and evacuations.

Q: Does the color silicone withstand direct contact for gasoline ?

A: Yes, quite. This high quality technical silicone is formulated to withstand hydrocarbons, competition fuel additives and 2-stroke mixing oil. It will not dissolve, will not be faded and retained all its elastic properties over the races.

Q: Is this article sold by the meter or in pre-cut kit ?

A: This article is sold in linear meter. By adjusting the quantity when ordering (ex: quantity = 2 to receive a single piece of 2 meters), you have the ideal length to redo the entirely left and right air circuits of your dell'orto carburetor as well as your overflows, while Keeping from the margin in your toolbox.
