Polaris Hawkeye 300 Problems

Despite the fact that the Hawkeye has a solid reputation, the quad’s most notable problems are primarily associated with the carburetor as well as the ignition system.

Some of the most typical problems and their simple solutions are described here below.

Won’t StartUse fresh fuel, and adjust the carburetor. 
Bogging Down of The EngineClan air filter, replace jets.
Smoke Coming OutUse fresh fuel, adjust the carburetor. 
Fuel Leaking OutRemove carburetor and fix internal damages.

1. Carburetor Issues

This is one of the common Polaris Hawkeye 300 issues. It wouldn’t idle at all when cold and took forever to heat up. 

The carburetor might clog, affecting ATV performance. The pilot jet usually clogs. The carb needle and seat may get stuck, allowing fuel to flow into the engine, and reducing its fuel efficiency

The Fix:

  • Turn off the carburetor, remove the jets, and clean them thoroughly, paying close attention to the pilot jet.
  • If the carburetor’s needle and seat become jammed, allowing gas to continuously feed the engine. First, try to turn the fuel off at the tank, and only then open the drain screw until the petrol stops leaking out of the drain pipe.

• If it helped, turn the fuel back on. Clean the carburetor’s needle and seat.

2. Engine Won’t Start

Not being able to start the engine or having it start slowly is a typical complaint among owners of the Polaris Hawkeye 300.

According to users, the Hawkeye 300 which has been idle for some time is even more difficult to start. It spins freely but does not start.

This issue typically arises when the gasoline tank is empty or when the fuel lines or fuel valves are clogged.

This occurs frequently in the Hawkeye 300 model year 2007.

The Fix:

  • Start by charging your battery, then use a multimeter to measure battery amps. Then you can verify the resistance of the capacitor charge coil.
  • Check the free-play of the throttle cable; there shouldn’t be too much movement.
  • Install a new plug with the appropriate spacing.
  • Ensure that the air filter is clean.

3. Bogging Down of The Engine

When under load, Polaris Hawkeye 300 becomes sluggish. The only time this occurs is when riding through the mountains; on flat land, everything goes well.

It’s not a problem going downhill, but going upwards is a problem.

This could be due to the airbox sucking in the steam. It may take 5 to 10 minutes of stalling, bogging and chugging before it clears.

The Fix:

  • Several 2006 Hawkeyes suffer from insufficient airflow due to a flawed airbox design. It is a constraint. The airflow to the carb can be improved by drilling holes in the top of the air box. It is essential for the carb to function normally.
  • Make sure the air filter is clean. If the problem persists, replace the air filter and jets.

4. Smoke Coming Out

After approximately a few seconds of running, the Hawkeye 300 emits clouds of white smoke.

Problems with smoking might arise when the air filter is unclean or when stale or contaminated fuel is used. In addition, a filthy carburetor is a typical cause of ATV smoke.

Polaris’s 2006 model year is affected by this problem.

The Fix:

If your Polaris is smoking, try switching to new, clean fuel as a first step in diagnosing and fixing the issue.

Repairing the issue may require replacing the air filter or adjusting the carburetor.

5. Fuel Leaking Out

Oil leaks are a common problem with the Polaris Hawkeye 300. The fuel usually leaks out of the nipple on the float cover. 

The carb’s bottom nipple has two purposes. When the float bowl overflows, it prevents fuel from entering the crankcase. It acts as a drain. 

If the screw is loosed it will allow the fuel to leak out of the carb. Also, prolonged use in rougher environments can cause oil leaks.

The Fix:

  • Remove and clean your carburetor. Disassemble the float and primary needle valve, put a Q-tip in a cordless drill, and polish the valve sleeve. Clean the needle tip, since dirt might cause fuel to keep filling the bowl. 
  • The defective float needle and seat must be repaired. Adjust the float.
  • It’s recommended that you wash your ATV and inspect it for cracks to see if that’s the issue. Spread sealant over the holes and wait for it to dry overnight.
