Why the Honda GX390 Electric Start Kit Is Necessary

The electric start kit saved me from that hassle by allowing me to start the engine effortlessly with just the push of a button.
Another reason I found the electric start kit necessary is the convenience it offers during cold mornings or after the engine has been sitting idle for a while. Manually pulling the starter in those situations can be frustrating and physically demanding. With the electric start kit, I can avoid all that struggle and get to work faster, which makes a big difference in productivity.

My Buying Guides on Honda Gx390 Electric Start Kit
When I first decided to upgrade my Honda GX390 engine with an electric start kit, I quickly realized there’s a lot to consider to make the right purchase. Here’s my step-by-step guide based on what I learned and experienced, so you can confidently choose the best electric start kit for your needs.
Understanding the Honda GX390 Engine
Before diving into electric start kits, I made sure I fully understood the Honda GX390 engine itself. It’s a popular 13 HP commercial engine used in various equipment like generators, water pumps, and pressure washers. Knowing the engine’s specs helped me find a compatible kit that fits perfectly without modifications.
Why Choose an Electric Start Kit?
I preferred an electric start kit because it saves time and effort compared to the traditional recoil start. It’s especially helpful if you use your equipment frequently or in tough conditions where quick starts matter. Plus, electric start kits can extend the engine’s lifespan by reducing wear on the recoil system.
Key Features to Look For
When shopping, I focused on these essential features:
- Compatibility: The kit must be specifically designed for the Honda GX390 model to ensure perfect fit and function.
- Quality of Components: Look for reliable starters, solenoids, and wiring to avoid frequent replacements. Genuine or OEM-quality parts are preferable.
- Ease of Installation: Some kits come with detailed instructions and all necessary hardware, which made my installation process smoother.
- Battery Requirements: Check what type and size of battery the kit needs, and whether it’s included or you need to buy separately.
- Warranty and Support: A good warranty and responsive customer service can save you headaches if issues arise.
Types of Electric Start Kits
There are mainly two types I found:
- Complete Electric Start Kit: Includes starter motor, solenoid, wiring harness, switch, and sometimes battery brackets. This is ideal if you want an all-in-one solution.
- Starter Motor Only: If you already have some components, you might just need the starter motor itself. This option can be more budget-friendly but requires more DIY knowledge.
Installation Tips from My Experience
Installing the kit was easier than I expected, but here are some tips I learned:
- Disconnect the battery before starting to avoid electrical shorts.
- Follow the wiring diagram carefully to connect solenoid, starter, and ignition switch.
- Secure all cables away from hot or moving parts.
- Test the starter motor separately before full installation to confirm it works.
- If you’re unsure, watching tutorial videos or consulting a mechanic can help a lot.
Where to Buy and Price Considerations
I found reputable sources online like Honda dealers, specialized engine part retailers, and trusted marketplaces. Prices vary widely—from around $150 to $300 or more depending on kit completeness and brand. I recommend investing in quality over the cheapest option to avoid future headaches.
Final Thoughts
Adding an electric start kit to my Honda GX390 engine was a game-changer in convenience and reliability. By focusing on compatibility, quality, and proper installation, I ensured my equipment runs smoothly and starts effortlessly every time. I hope my guide helps you make an informed choice and enjoy the same benefits!
