Husqvarna line trimmers are powered by a mixture of two-stroke oil and fuel. The correct ratio of fuel to oil is 50:1, which is equivalent to 2%. It is important to mix the fuel thoroughly before filling the machine's tank and to not mix more than one month's supply at a time. The ethanol in the fuel can bond with moisture in the system and cause corrosion.

Ethanol in the fuel can cause corrosion
The fuel and oil mixture for a Husqvarna line trimmer should always be 2% (50:1). It is recommended that you use Husqvarna oil mixtures.
It is important to follow the correct fuel mixture ratio as specified by the manufacturer. This information can be found in the operator's manual for your product. By following the recommended fuel mixture and usage guidelines, you can help prevent issues related to ethanol corrosion in your Husqvarna line trimmer.
Additionally, using fuel stabilizers can help extend the life of the fuel mixture and reduce the risk of corrosion. Fuel stabilizers work by preventing the ethanol in the fuel from bonding with moisture, thus inhibiting the corrosion process. It is also advisable to use fresh fuel and to avoid storing the trimmer with fuel in the tank for extended periods.
If corrosion does occur, there are products on the market that can help clean and restore the fuel system. One such product is called 'Mechanic in a Bottle', which has been reported to have some success in cleaning out the gunk in the system. However, in severe cases, it may be necessary to disassemble the carburettor and clean or replace affected parts, such as gaskets.
