If your leaf blower only runs on full choke, it's likely due to a fuel mixture issue. This can happen if the carburetor is clogged or the fuel mix is incorrect. To solve this, start by cleaning the carburetor using carb cleaner. If that doesn't work, check the fuel mixture to make sure it's properly balanced. Adjustments or replacements may be necessary if these solutions don't resolve the problem. Lastly, check the air filter and replace it if dirty, to ensure proper air flow.
FAQs & Answers
- Why does my leaf blower only run when the choke is fully engaged? When a leaf blower only runs on full choke, it typically indicates a clogged carburetor or an improper fuel mixture, restricting normal operation. Cleaning the carburetor and checking the fuel mix usually resolves the issue.
