How many horsepower is a 42cc chainsaw?
A 42cc gas chainsaw is typically in the 2.0 to 2.5 horsepower range. For your Craftsman 944415361 chainsaw, horsepower varies by engine design and tuning, but 42cc homeowner saws commonly land around about 2.3 HP.
Most 42cc 2-cycle chainsaws are built for limbing and light to medium cutting, so they are tuned for usable torque rather than maximum peak HP.
- Typical output: 2.0 to 2.5 HP
- Common “advertised” value: about 2.3 HP
- Real-world feel depends heavily on chain sharpness, bar length, and carburetor condition
Even with the same displacement (42cc), performance can differ.
- Carburetor tuning and condition (lean/rich mix, clogged passages)
- Fuel delivery (cracked fuel lines, air leaks, restricted fuel pickup)
- Exhaust flow (spark arrestor screen plugged with carbon)
- Compression (piston/ring wear)
- Cutting setup (chain type, sharpness, and bar length)
If your Craftsman 944415361 bogs down, surges, or won’t rev cleanly, these parts are common fixes:
| Symptom | Common cause | Example part on this model page |
|---|---|---|
| Won’t accelerate, dies on throttle | Fuel line cracked or soft | Poulan lawn & garden equipment fuel line, small 530069247 |
| Hard starting, needs lots of choking | Primer bulb leaking | Ayp lawn & garden equipment engine carburetor primer bulb 530047721 |
| Runs, then loses power as it warms | Spark arrestor restricted | Ayp chainsaw spark arrestor 545006056 |
Horsepower is only one part of cutting performance. A sharp chain, correct bar length (many 42cc saws run a 16-inch bar), and a clean fuel and exhaust system often make a bigger difference than chasing a specific HP number.

How to look up chainsaw serial number?
On the Craftsman chainsaw model 944415361, the serial number is typically on a sticker or stamped tag near the oil fill cap or on the bar side of the saw under the handle. Once you find it, record it exactly as shown (letters, numbers, and any dashes).
Look in these common spots first:
- Near the oil fill cap on the body of the saw
- Bar side of the saw, under or behind the front handle
- Starter housing area (recoil cover) if the label is not near the oil tank
- Rear handle area near the throttle trigger (less common)
We use the serial number mainly to identify production details when you are:
- Confirming the correct replacement part version
- Comparing a part already on the saw to the parts list
- Troubleshooting issues tied to fuel delivery, starting, or oiling
If you are ordering parts, the model number (944415361) is the key identifier; the serial number is a helpful secondary detail.
Use the serial number to double-check what you see on the saw before ordering:
- Inspect fuel lines for cracking or softness; match sizes to the parts list
- Check the primer bulb for splits or stiffness
- Verify the guide bar and chain size before replacing
- Note any carburetor markings if you suspect a fuel/starting issue
| If you’re trying to fix… | Serial number helps most when… | Common parts to inspect |
|---|---|---|
| Hard starting | You suspect a fuel system mismatch | Fuel lines, primer bulb, carburetor |
| Fuel leaks | You need to confirm routing and fittings | Fuel line fitting, fuel lines |
| Poor chain oiling | You are matching oil system parts | Oil pump, oil tank vent |
Serial numbers can help distinguish small production changes that affect fit. That is especially useful on fuel system and oiling components where hose routing, fittings, and assemblies must match exactly.

What is the L and H on a Craftsman chainsaw?
On your Craftsman 944415361 gas chainsaw, L and H are the carburetor mixture adjustment screws: L controls the low-speed (idle to midrange) fuel mixture, and H controls the high-speed (wide-open throttle) fuel mixture. These settings affect starting, acceleration, and top-end power.
- L (low-speed mixture): Affects starting, idle quality, and how the saw accelerates when you squeeze the throttle.
- H (high-speed mixture): Affects power at full throttle and engine temperature under load.
- Idle speed screw (often marked T, LA, or S): Sets how fast the engine idles; it does not directly change the fuel mixture.
- Warm the engine for a few minutes before adjusting.
- Turn screws in small steps (about 1/8 turn at a time).
- Adjust L for smooth idle and crisp acceleration (no bogging).
- Adjust idle speed so the engine stays running but the chain does not creep.
- Adjust H only enough for strong cutting power; too lean can overheat the engine.
| Symptom | Most common cause | What to adjust/check first |
|---|---|---|
| Won’t idle, dies at idle | Low-speed mixture off, air leak, dirty carb | L screw, then fuel lines/primer |
| Bogging on throttle | Too lean on low-speed circuit | L screw slightly richer |
| Chain spins at idle | Idle speed set too high | Idle speed screw down |
| Runs hot, lacks power | High-speed mixture too lean | H screw slightly richer |
Correct L and H settings keep your 944415361 starting reliably, accelerating cleanly, and running cooler under load. A saw tuned too lean can run hot and score the piston and cylinder, while a saw tuned too rich can foul the spark arrestor and waste fuel.
If tuning does not help, these parts commonly cause similar symptoms:
- Cracked or soft fuel lines: poulan lawn & garden equipment fuel line, small 530069247, ayp lawn & garden equipment fuel line, large 530069216
- Primer bulb not pulling fuel: ayp lawn & garden equipment engine carburetor primer bulb 530047721
- Carburetor wear or internal blockage: carburetor z 545070601
- Plugged spark arrestor screen: ayp chainsaw spark arrestor 545006056

What model number is a Craftsman 16 36cc chainsaw?
For the Craftsman gas chainsaw shown on this page, the model number is 944415361. If you are looking at a different Craftsman 16-inch, 36cc chainsaw, the model number is printed on the saw’s ID tag and is the best match to use when ordering parts.
Look for an ID tag or sticker on the chainsaw body; common locations include:
- The rear handle area (near the trigger)
- The starter housing (recoil cover)
- Near the bar mount/clutch cover area
- On the underside of the fuel tank housing
Craftsman sold multiple 16-inch bar, 36cc class chainsaws over the years. The model number is what ties your saw to the correct parts list, such as fuel lines, primer bulb, carburetor, chain, and bar.
Even when two saws look similar, these items often differ by model:
- Fuel line sizes and routing
- Carburetor and carburetor adapter parts
- Primer bulb style
- Chain pitch/gauge and drive link count
- Bar mount pattern and bar plate
| Part type | Example part for model 944415361 | What it affects |
|---|---|---|
| Fuel line | Poulan lawn & garden equipment fuel line, small 530069247 | Fuel delivery, starting, running |
| Primer bulb | Ayp lawn & garden equipment engine carburetor primer bulb 530047721 | Cold starts, priming fuel |
| Chain | Chain 91PX056G | Cutting performance, fit on bar |
Use the full model number from the ID tag (not the bar length or engine size) when searching parts. If your saw is hard to start, we recommend following the checks in tips for a hard to start chainsaw before replacing parts.
