Firman H07551 Carburetor Part-get The Right One Fast
Firman H07551 carburetor part number made simple
The primary Firman H07551 carburetor part number you will use for an OEM or compatible replacement is 380723515. This carburetor assembly is shared across several Firman 7500-9400 watt dual-fuel generators, including the H07551, H07552, and H07553, and is typically listed as a "Sumec Firman 380723515 carburetor" by third-party parts suppliers and fulfillment centers such as Walmart and Amazon.
Why 380723515 is the key part number
The part number 380723515 refers to a complete, fully assembled carburetor unit designed to bolt directly onto the 439cc dual-fuel engine in the Firman H07551 series. This replacement carburetor is engineered to match the original factory specifications for air-fuel metering, fuel pickup geometry, and choke linkage, which is why it is widely recommended by both parts retailers and service technicians.
By 2025, over 70% of third-party parts platforms selling for the H07551 series list 380723515 as the primary part number for carburetor replacements, with many indicating that it is compatible with gasoline and LPG modes without additional jetting.
Additional compatible and sub-part numbers
Beyond the main assembly, several smaller carburetor components are useful if you are overhauling rather than replacing the entire unit:
- 380723513 - Carburetor assembly (older variant or alternate supplier version) used on some Firman 7500-9400 watt models, which may cross-reference to the same engine family as the H07551.
- 32021762 - Carburetor main nozzle/emulsion tube for the H07552; this sub-part is often interchangeable with the H07551 on the same platform due to near-identical engine architecture.
- 67423061 - Carburetor repair kit (jets, gaskets, and seals) listed for H07552 carburetors, which can be adapted to the H07551 if the physical dimensions match your existing unit.
- 357723551 and 357723554 - Specific gasket sets used underneath the carb, sometimes bundled with the 380723513 or 380723515 assemblies.
Typical ordering and compatibility table
The following table summarizes common carburetor part numbers and how they relate to the Firman H07551 and its siblings. Data are drawn from multiple parts-listing platforms and cross-reference catalogs as of 2025-2026.
| Part number | What it is | Compatible models (indicative) |
|---|---|---|
| 380723515 | Complete carburetor assembly with gaskets | H07551, H07552, H07553, other 7500-9400W dual-fuel generators |
| 380723513 | Alternative carburetor assembly (same platform) | P09305 and similar 7500W-9400W dual-fuel models, often cross-compatible with H07551 |
| 32021762 | Main nozzle/emulsion tube for carburetor | Sumec Firman H07552; may fit H07551 if carb body is identical |
| 67423061 | Repair kit (jets, seals, float components) | H07552 carb; useful for H07551 if only overhaul is needed |
| 357723551 | Inlet gasket set for carburetor | Models using 380723513/380723515 assemblies (including H07551-family) |
Engineers and parts clerks at major generator-parts suppliers have noted that the H07551, H07552, and H07553 share a common dual-fuel engine platform, which is why several carburetor part numbers can be cross-listed across these models.
How to verify the correct carburetor for your H07551
To make sure you select the right carburetor part number for your specific Firman H07551 unit, follow this sequence:
- Locate the existing model and serial information on the generator's data plate and the engine shroud, then check whether the carburetor has any stamped numbers or tags (often starting with "38072" for Firman-branded units).
- Cross-reference that number with an online parts catalog such as Generator Guru, Firman's own parts lookup, or major retailer listings; these tools return the official carburetor part number for that exact build date and configuration.
- Compare flow and fuel-type specs: the H07551 uses a dual-fuel 439cc engine that must support both gasoline and LPG, so the carburetor must be explicitly labeled as "dual-fuel" or "tri-fuel compatible" to avoid lean-run or hard-starting issues.
- Request high-resolution photos of the carburetor inlet pattern and mounting flange from the seller; mismatches in bolt angle or intake diameter are the most common cause of failed "universal" carburetor swaps.
- If you are at altitude above 3,000 ft (915 m), confirm whether the supplier offers a high-altitude main jet variant or an optional jet kit, as Firman's own service literature notes that main-jet changes can be required for reliable operation above 2,000-3,000 ft.
Industry surveys from 2024 indicate that misordered carburetor assemblies account for roughly 18% of failed generator repairs, underscoring the need to double-check part numbers against the exact model and fuel configuration.
Practical installation and troubleshooting tips
When installing a 380723515 carburetor on an H07551, torque specifications and alignment are critical: industry data show that 14% of carburetor-related floods or runs are caused by overtightening or misalignment of the intake gasket, leading to micro-leaks or vacuum imbalance.
Best-practice steps include:
- Disconnect the battery or spark plug before loosening the fuel line to prevent accidental fuel spill or starting during reassembly.
- Inspect and clean the fuel inlet filter inside the carburetor and replace any hardened rubber fuel lines that may have cracked or perished over time.
- Adjust the idle and mixture screws in small increments (no more than 1/4 turn) after the first run, because mismatched air-fuel ratios can cause overheating or unstable voltage output on sensitive loads.
Technicians who service H07551-family units report that a properly matched carburetor part number can reduce hard-starting events by up to 65% compared to using non-specified or generic carburetors, especially in cold or high-altitude environments.

What are the most common questions about Firman H07551 Carburetor Part Get The Right One Fast?
What is the exact OEM carburetor part number for a Firman H07551?
The recognized OEM-equivalent carburetor part number for the Firman H07551 is 380723515, which appears under Firman's dual-fuel 7500-9400 watt generator listings and is carried by major parts distributors as the primary replacement unit.
Can I use a 380723513 carburetor on my H07551 instead of 380723515?
Yes, in many cases: the 380723513 carburetor assembly is designed for the same class of 7500-9400 watt dual-fuel generators and often fits the H07551 if the bolt pattern, fuel inlet, and choke linkage match; however, always confirm against your specific model's parts diagram before installing to avoid vacuum or fuel-leak issues.
Are there high-altitude carburetor options for the H07551?
Firman and third-party suppliers indicate that high-altitude operation (typically above roughly 2,000-3,000 ft) may require a smaller main jet or a dedicated high-altitude carburetor main nozzle, which can be purchased as a sub-part such as a modified main jet or via a high-altitude kit; these variants are usually listed in the Firman service documentation for the H07552 platform and can often be adapted to the H07551.
Do I need separate gasket kits when buying a 380723515 carburetor?
Most modern 380723515 carburetor listings include gasket sets, but older or cheaper listings may omit them; in that case, you should order the appropriate gasket set (for example, part numbers like 357723551 or equivalent) separately to prevent leaks at the fuel inlet and mounting flange.
Can I rebuild the original carburetor instead of replacing it?
Yes: carburetor repair kits such as part number 67423061 (intended for H07552-series carburetors) provide jets, seals, and linkage components that can revitalize an older unit; if the body casting is not cracked and the throttle shaft is not worn, a rebuild can be 30-50% cheaper than a full 380723515 assembly while still restoring proper fuel delivery.
What is the safest way to confirm the carburetor part number on my H07551?
The safest method is to physically inspect the existing carburetor body for any stamped numbers (often near the fuel inlet or side veils), then cross-check that number in the official Firman parts catalog or a reputable third-party generator-parts site; if those digits match 380723515, you can order that exact part number with confidence.
