Why won't my McCulloch MT 260 CLS Trimmer start?
- JJerry BestAug 1, 2025
Your McCulloch Trimmer might not start due to several reasons. You may be using incorrect starting procedures, so follow the instructions in the User Manual. Another cause could be a fouled spark plug, in which case you should clean, gap, or replace the plug. Also, a blocked fuel filter can prevent starting, so replace the fuel filter. Finally, the carburetor mixture adjustment setting might be incorrect, and you should have it adjusted by an Authorized Service Center.
