Suitable for Husqvarna 365 372 chainsaws: adjusting screw, carburetor adjusting screw, L-type needle, H-type needle, idle screw, carburetor screw, accessories for petrol chainsaws.--DTEKGAZ

The carburetor adjustment screws (L-needle, H-needle, and idle screw) are precision components of the chainsaw's fuel system. Although small, they significantly influence engine performance under various operating conditions. The L-needle regulates the air-fuel mixture at low RPMs, the H-needle at high RPMs, and the idle screw the idle speed. If these screws are lost, damaged, or have worn threads, precise carburetor adjustment is no longer possible. This leads to problems such as starting difficulties, rough idling, poor acceleration, increased fuel consumption, power loss, and even engine stalling. More seriously, an incorrect mixture setting can also lead to engine overheating or cylinder bore damage. This product was specifically designed for the carburetors of the Husqvarna 365 and 372 chainsaws and is precision-machined from high-quality metal alloys. The three screws are manufactured to original specifications and feature a high-precision thread, a perfect fit on the carburetor body, smooth rotation, and a precise feel for optimal fine-tuning. The L and H needles have adjustment grooves on their heads for precise adjustment with a screwdriver. The precise taper of their tips ensures a linear fuel flow regardless of the angle of rotation, allowing for accurate and controllable adjustment. The idle screw has the same shape as the original, ensuring precise engagement of the carburetor throttle lever for a stable idle. Its surface is coated with a rust-resistant finish that resists corrosion from fuel and moisture, preventing rust and seizing during extended use. Installing this adjustment screw will restore your chainsaw's carburetor to optimal settings, maximizing performance and fuel consumption. As a high-quality replacement part, this product offers an economical repair solution. It is recommended to check the condition of the adjustment screw when replacing, cleaning, or servicing the carburetor and replace it immediately if damaged. Please observe the manufacturer's technical specifications when adjusting the carburetor, or have the work carried out by a professional to ensure optimal performance and avoid engine damage.
