How many cc's is a Poulan Wild Thing 2775?
The Poulan 2775 (Wild Thing) is a 40 cc gas chainsaw. This matches the 2750/2775 family covered in the Poulan 2775 owner's manual, and it is the engine size you will use when selecting tune-up parts and setting the correct 2-cycle fuel mix.
- Engine displacement: 40 cc
- Fuel type: unleaded gasoline mixed with 2-cycle air-cooled engine oil
- Fuel mix ratio: 40:1 (3.2 oz oil per 1 gallon gas)
- Bar and chain lubrication: automatic oiler; keep the oil tank filled
A 40 cc saw is sensitive to fuel quality and airflow. If it runs rough, lacks power, or is hard to start, these items are the first to check:
- Air filter condition (clean or replace as needed)
- Spark plug condition and gap (inspect, clean, replace if fouled)
- Fuel freshness and correct 40:1 mix
- Chain brake fully disengaged before testing power
- Bar oil level and oil flow to the bar and chain
If you need a common maintenance part for this model, the air filter 545057701 is a frequent replacement when the engine bogs down or won’t accelerate.
| Gasoline amount | 2-cycle oil amount | Mix ratio |
|---|---|---|
| 1 gallon | 3.2 oz | 40:1 |
| 1/2 gallon | 1.6 oz | 40:1 |
| 1 quart | 0.8 oz | 40:1 |
Using the correct 40 cc spec and the correct 40:1 fuel mixture helps prevent hard starting, excessive smoke, poor acceleration, and premature engine wear. It also helps you choose the right Poulan chainsaw parts (filters, ignition parts, and fuel system components) for the 2775 platform.

Is 40:1 or 50:1 mix for chainsaws?
For the Poulan 2775 gas chainsaw, we use a 40:1 fuel mix: 3.2 oz of quality synthetic 2-cycle air-cooled engine oil per 1 gallon of unleaded gasoline. This is the factory ratio listed in the Poulan 2775 owner's manual.
Use 40:1 every time you mix fuel.
- Mix 3.2 oz 2-cycle oil with 1 gallon of unleaded gasoline
- Use synthetic 2-cycle air-cooled engine oil (not automotive oil, not marine/boat oil)
- Shake the fuel container briefly after mixing so the oil blends evenly
- Use fresh fuel; old fuel can cause hard starting and rough running
- Tighten the fuel cap securely and refuel carefully
| Mix ratio | Oil per 1 gallon gas | Typical use case |
|---|---|---|
| 40:1 | 3.2 oz | Many Poulan and older 2-cycle designs; higher lubrication margin |
| 50:1 | 2.6 oz | Some newer 2-cycle engines designed for leaner oil ratios |
Running the correct oil ratio protects the piston, cylinder, and crank bearings from heat and friction. On the Poulan 2775, using 50:1 reduces oil content below the specified 40:1 mix and can increase wear during heavy cutting.
Fuel ratio is only one piece of the puzzle. These checks often help:
- Replace a dirty air filter 545057701
- Install a new spark plug 503235111
- Check for a restricted fuel filter or cracked fuel lines
- Verify the choke and throttle linkage move freely

What are the common problems with Poulan chainsaws?
Common problems on the Poulan 2775 gas chainsaw usually trace back to fuel quality and routine maintenance: old ethanol-blended fuel can damage the fuel system during storage, and a dirty air filter or incorrect carburetor idle setting can cause hard starting, rough running, low power, or the chain creeping at idle. See the 2775 owner's manual for model-specific safety and adjustment guidance.
- Won’t start or starts then dies: stale fuel, fuel system varnish after storage, restricted fuel flow
- Runs rough or won’t accelerate: dirty air filter, fouled spark plug, carburetor needs adjustment
- Smokes excessively: too much oil mixed in the fuel (incorrect fuel mixture)
- Chain moves at idle: idle speed set too high, clutch needs service
- Bar and chain overheat or smoke: oil tank low, oiler not delivering enough oil, wrong oil viscosity in cold weather
- Drain old fuel and refill with fresh, properly mixed fuel.
- Inspect and clean or replace the air filter; a clogged filter can cause power loss.
- Check the chain brake is fully disengaged before testing acceleration.
- Confirm bar and chain oil is flowing; keep the oil tank filled.
- If the chain creeps at idle, follow the carburetor idle adjustment procedure in the manual.
| Symptom | Part to inspect/replace | Model-matched example |
|---|---|---|
| Low power, poor acceleration | Air filter | Air filter 545057701 |
| Fuel starvation, hard starting | Fuel filter | Craftsman lawn & garden equipment engine fuel filter 530095646 |
| Chain creeps, poor drive | Clutch | Chainsaw clutch 530014949 |
Alcohol-blended fuel can attract moisture and form acids during storage. For storage periods of 30 days or longer, we recommend emptying the fuel system (drain tank, then run the engine until the fuel lines and carburetor are empty) and using fresh fuel next season.
Fuel-related issues and lubrication problems can quickly turn into expensive damage (scored cylinder, ruined bar and chain, clutch wear). Keeping the fuel fresh, the air filter clean, and the oiler working protects performance and safety.
