How to fix a Demon Other engine that cranks but won't start?
- DDavid RiceAug 9, 2025
If your Demon Other engine cranks but doesn't start, several factors could be at play. First, examine the choke adjustment and ensure nothing is binding; adjust as needed. Also, check the choke linkage for binding and lubricate it with WD-40, inspecting for any bent components and adjusting if necessary. Verify fuel delivery by checking for plugged filters, clogged lines, a faulty pump, a stuck needle and seat, and adequate fuel pressure. A defective or worn-out accelerator pump could also be the culprit, often due to bad or dirty gas, vacuum leaks, or ignition issues, so consider replacing it. Finally, rule out spark or engine problems like bad compression by diagnosing and correcting any identified issues.
