Troubleshooting

Think of a potato cannon like a science project. It's easy and fun, but requires some tinkering.

1. Make sure the barrel is fully sealed with potato.

2. Recommended spray times should be used as general guidelines.

3. Altitude and weather conditions play a significant role in the fuel / air mixture.

4. It may be necessary to increase or decrease propellant quantities to obtain desired results.

5. It's takes a bit of practice to find your sweet spot.

6. You can adjust the rubber ring and/or the metal prong on your igniter to maximize the arc / spark of the igniter.
