Compatibility
| Engine Architecture | Applications (125cc–170cc) |
|---|---|

Installation Tip
Before mounting, inspect your rubber intake manifold boot for cracks or dry rot — even a small air leak will cause a lean condition that throws off tuning. After installation, let the engine warm up fully (5–10 minutes) so the electric choke closes completely before adjusting idle speed or the enrichment screw.
