### Briggs & Stratton 58379 Antique FH Air-Cooled Gas Engine Overview
The **Briggs & Stratton 58379 Antique FH** is a classic air-cooled, single-cylinder, horizontal-shaft gasoline engine. It was originally designed for small generators, pumps, and other applications requiring reliable, low-maintenance power. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.
---
### **Pros**
1. **Proven Reliability and Durability**
The Briggs & Stratton FH series is well-known for its robust construction and long service life, especially when properly maintained. Many of these engines have lasted decades with minimal wear, making them ideal for collectors or those seeking a backup power source.
2. **Simple and Easy to Maintain**
The engine features straightforward mechanics with fewer components than modern counterparts. Basic maintenance such as oil changes, spark plug replacements, and carburetor adjustments can be done with basic tools. This makes it accessible for DIY enthusiasts or those without advanced mechanical skills.
3. **Air-Cooled Design**
No need for a radiator or coolant system, reducing complexity and potential failure points. This also means it can operate in a wider range of temperatures without overheating concerns.
4. **Compatibility with Vintage Equipment**
The FH engine is designed to fit into older generators, pumps, and machinery, making it a viable option for restoring or repurposing antique equipment. It s also a popular choice for homemade projects like water pumps, well drills, or even small-scale industrial applications.
5. **Lower Operating Costs**
Gasoline is relatively inexpensive compared to other fuels, and the engine consumes fuel efficiently for its power output. Parts are also widely available, though some may require sourcing from specialty suppliers.
6. **Historical and Collectible Value**
For enthusiasts, antique Briggs & Stratton engines hold nostalgic and collector value. They are often sought after for their historical significance and craftsmanship, which can appreciate over time.
7. **Versatility**
The horizontal-shaft design allows for easy integration into various applications, including stationary generators, portable power setups, or even as a power source for custom-built devices.
8. **Minimal Vibration and Noise (Compared to Some Alternatives)**
While not silent, the FH engine operates more smoothly than many older engines, reducing wear on connected equipment and making it more suitable for prolonged use.
---
### **Cons**
1. **Age and Wear**
As an antique engine, it may already exhibit signs of wear, such as worn piston rings, cracked gaskets, or a fouled carburetor. Without proper maintenance records, the true condition of the engine is unknown, which could lead to unexpected repairs or failure.
2. **Limited Power Output**
The 58379 model typically produces around **1/2 to 3/4 horsepower**, which is sufficient for small tasks but insufficient for heavy-duty applications like large generators or industrial machinery. This limits its practical use for modern high-demand projects.
3. **Fuel and Emissions Concerns**
Older engines like this one often have carburetions that are less efficient and may produce more emissions than modern fuel-injected engines. They also require leaded gasoline in some cases, which is increasingly difficult to obtain. Running it on modern unleaded fuel may require modifications.
4. **Parts Availability**
While Briggs & Stratton parts are still available, some components such as specific gaskets, seals, or carburetor parts may be harder to find. Prices for rare parts can also be higher than for new engines.
5. **Starting Difficulty**
Antique engines, especially those with recoil starters, can be harder to start in cold weather or if the battery (if equipped) is weak. Some may require manual cranking, which can be labor-intensive.
6. **Potential for Hidden Damage**
Without a thorough inspection, the engine could have internal damage (e.g., bent rods, worn bearings, or cracked blocks) that isn t immediately visible. This could lead to costly repairs or a complete engine replacement.
7. **No Modern Safety Features**
Older engines lack modern safety features such as automatic shutoff mechanisms, vibration sensors, or low-oil alerts. This means the user must manually monitor the engine s operation, increasing the risk of damage or accidents.
8. **Environmental Regulations**
In some areas, operating older engines may be restricted due to emissions standards. Local laws should be checked before use, especially for prolonged operation.
9. **Learning Curve for Restoration**
If the engine is in poor condition, restoring it to working order may require mechanical skills beyond basic maintenance. This could involve machining, welding, or sourcing replacement parts.
10. **Resale Value Depends on Condition**
While some antique engines appreciate in value, others depreciate quickly if they are not well-maintained. The resale market is niche, and finding a buyer may be difficult unless the engine is in pristine condition or has historical significance.
---
### **Conclusion**
The **Briggs & Stratton 58379 Antique FH** engine is a fantastic choice for enthusiasts, collectors, or those working on vintage machinery projects. Its reliability, simplicity, and historical value make it a rewarding purchase for the right buyer. However, it is not ideal for modern high-power applications due to its limited output and age-related limitations.
If you are purchasing this engine for a **restoration project, a backup power source, or a hobbyist application**, it can be an excellent investment with proper care. On the other hand, if you need a **high-performance, low-maintenance engine for heavy-duty or commercial use**, a modern replacement would be a better choice.
---
### **Recommendation**
1. **Buy with a Thorough Inspection**
Before purchasing, have the engine inspected by a mechanic familiar with vintage Briggs & Stratton models. Look for signs of internal wear, compression leaks, and overall structural integrity. Request maintenance records if available.
2. **Consider the Intended Use**
- **For restoration or hobby projects:** The FH engine is a great fit if you enjoy working with vintage machinery.
- **For a backup generator or small power needs:** It can work well if you are prepared for occasional maintenance.
- **For heavy-duty or commercial use:** Avoid this engine; opt for a modern, high-efficiency model instead.
3. **Budget for Repairs and Maintenance**
Antique engines require regular upkeep. Factor in costs for oil changes, carburetor cleaning, spark plug replacements, and potential major repairs (e.g., piston replacement, crankshaft machining).
4. **Source Parts in Advance**
If you plan to restore the engine, order critical parts (e.g., gaskets, seals, carburetor components) before starting work to avoid delays.
5. **Check Local Regulations**
Ensure that operating the engine complies with emissions and noise ordinances in your area, especially if you plan to use it frequently.
6. **Consider a Modern Alternative if Needed**
If your primary goal is reliable, high-performance power, a modern Briggs & Stratton engine (e.g., the **105657** or **105658** series) or a small diesel generator may be a better long-term investment.
---
### **Final Verdict**
The **Briggs & Stratton 58379 Antique FH** is a **strong choice for collectors, restorers, and hobbyists** who appreciate its historical value and simplicity. For most modern practical applications, however, a newer engine would be more practical. If you proceed with this purchase, prioritize condition, maintenance, and compatibility with your project to maximize its lifespan and enjoyment.
Details:
Spark plug is broken. No compression. I am pretty sure this engine has not been ran ever since it was retired off the farm years ago. Spark plug wire is brittle.
Rocker arm stand has been welded. Engine does turn over. The kick start mount on the gas tank base is broken. Great for parts or restoration.
This item Will need completely torn down and gone through. Nice brass tag. I can hear a lot of air go past the exhaust valve when turning it over. Both valves are not stuck.
See all pictures for the absolute best. Neat old Briggs Stratton model FH straight fin Aircooled gas engine. Wires going to the kill switch are broken. The threads for the exhaust pipe are bad/rusted.
Lots of dirt and grease build up. Carburetor looks to be in pretty solid condition. Please see pictures for the absolute best.
