Pull-start engines are widely used in nitro RC cars; they are lighter and simpler than electric-start engines, and they’re also more reliable. But pull-starts can fail due to wear and tear, so it’s important to know how to fix them when something goes wrong. Fortunately, repairing a pull-start is not difficult and can be done with a few simple tools. Here’s what you need to do:
- Check the Starter Grip – The starter grip is the handle that you use to start the engine, and it’s connected to the pull-start mechanism. If it’s loose or broken, then it won’t engage the engine properly. Check it for any signs of damage or wear, and if necessary replace it.
- Check the Rope – The rope is the cord that connects the starter grip to the mechanism.
If it’s worn or frayed then it won’t be able to engage the engine properly. Check for any signs of damage or wear, and if necessary replace it.
- Check the Spring – The spring is responsible for providing tension on the rope so that it engages properly with the engine. Check for any signs of wear or damage, and if necessary replace it.
- Clean & Lubricate – Once you have checked all of the parts for any signs of wear or damage, clean them thoroughly with a cloth. Then lubricate them with a light lubricant such as WD-40.
- Reassemble – Once all parts have been cleaned & lubricated, reassemble them in their proper order according to your car’s instruction manual.
After following these steps, your pull-start should be fixed and ready to go! Pull-starts can fail due to normal wear and tear over time but following these steps should help you fix your pull start quickly and easily.
Conclusion:
Pull starts on nitro RC cars can fail due to normal wear & tear over time but fortunately fixing one isn’t difficult. By checking each part for any signs of damage or wear, cleaning & lubricating them as needed, then reassembling everything together in its proper order should have your pull start running again in no time.
