How Single-Stage Works

Single-stage snowblowers differ from two-stage:

  • Auger contacts ground - Rubber paddles touch surface
  • Auger propels unit - No separate wheel drive
  • Lighter weight - Easier to maneuver
  • Best for light snow - Under 8” and not too wet

Engine Problems

Won’t Start

Most common cause: Old fuel from summer storage.

Troubleshooting sequence:

  1. Check fuel - Fresh gas under 30 days old?
  2. Prime bulb - Press 2-3 times until fuel visible
  3. Set choke - Full choke for cold start
  4. Check spark plug - Remove and inspect
  5. Try electric start - If pull start fails

Starting procedure:

  1. Turn fuel valve ON (if equipped)
  2. Set choke to FULL
  3. Prime 2-3 times
  4. Set throttle to FAST
  5. Pull cord or press electric start
  6. Move choke to RUN after engine warms

If still won’t start:

  • Spray starting fluid into carburetor intake
  • If fires briefly = carburetor problem
  • If nothing = spark or compression issue

See our snowblower won’t start guide for detailed troubleshooting.

Hard Starting After Storage

Old fuel varnishes carburetors quickly. This is the #1 seasonal problem.

Fix:

  1. Drain old fuel from tank
  2. Remove and drain carburetor bowl
  3. Add fresh fuel
  4. Try starting
  5. If still won’t start, carburetor cleaning needed

See our how to clean a carburetor guide.

Engine Surges

Engine RPM rises and falls repeatedly.

Causes:

  1. Dirty carburetor jets
  2. Poor fuel quality
  3. Air leak at intake gasket
  4. Governor linkage issue

Fix:

  • Replace fuel with fresh
  • Clean carburetor thoroughly
  • Check intake gasket

Engine Lacks Power

Causes:

  1. Old or bad fuel
  2. Dirty air filter
  3. Worn spark plug
  4. Clogged exhaust
  5. Carburetor running lean

Check order:

  1. Replace fuel
  2. Clean/replace air filter
  3. Install new spark plug
  4. Service carburetor

Electric Start Issues

Won’t crank with electric start:

  • Check outlet power
  • Verify cord plugged in fully
  • Cold affects extension cord efficiency (use heavy gauge)
  • Starter motor failure (rare)

Electric start works but recoil doesn’t:

  • Starter rope broken
  • Recoil mechanism stuck

Auger System Issues

Auger Won’t Turn

Check in order:

  1. Auger control engaged - Lever must be held
  2. Auger belt - Inspect for wear or breakage
  3. Paddles frozen - Ice blocking movement
  4. Cable adjustment - Control cable may need adjustment

Rubber Paddles

Single-stage snowblowers use rubber paddles that wear over time.

Signs of worn paddles:

  • Reduced throwing distance
  • Leaving snow behind
  • Machine won’t self-propel
  • Paddles don’t contact ground

When to replace: When paddles have less than 1/4” clearance from housing. Most paddles have wear indicators.

Paddle replacement:

  1. Remove auger cover (few bolts)
  2. Remove old paddle bolts
  3. Install new paddles
  4. Verify even spacing
  5. Reinstall cover

Paddle life: 2-5 seasons depending on:

  • Surface type (gravel wears faster)
  • Hours of use
  • Snow conditions

Scraper Bar

The scraper bar clears the surface behind the auger.

Adjustment:

  • Should ride just above ground
  • Too high = snow left behind
  • Too low = excessive wear

Replacement: When worn thin or uneven. Usually every 3-5 seasons.

Weak Snow Throwing

Causes:

  1. Worn paddles (most common)
  2. Engine not at full RPM
  3. Chute partially blocked
  4. Auger belt slipping
  5. Wet heavy snow (inherent limitation)

Fixes:

  • Replace worn paddles
  • Run at full throttle
  • Clear any chute blockage
  • Check belt tension/condition

Auger Belt

Signs of worn belt:

  • Slipping under load
  • Squealing noise
  • Visible cracks or wear
  • Auger slow to engage

Replacement: Annual inspection recommended. Replace if worn.

Drive and Propulsion

Won’t Move Forward

Single-stage snowblowers are propelled by the auger paddles gripping the ground.

Causes:

  1. Paddles worn (most common) - Can’t grip surface
  2. Auger not engaging - Control or belt issue
  3. Frozen auger - Ice preventing movement
  4. Belt broken or slipping

Note: Single-stage units require more pushing/pulling than two-stage machines. This is normal.

Moves Too Fast or Too Slow

Too fast:

  • Throttle at full when not needed
  • Paddles new and aggressive

Too slow:

  • Paddles worn
  • Belt slipping
  • Engine underpowered (RPM issue)

Chute Controls

Chute Won’t Rotate

Manual chute causes:

  1. Ice/snow buildup - Most common
  2. Crank mechanism frozen
  3. Cable or rod broken
  4. Gears stripped

Fixes:

  • Clear ice with brush or warm water
  • Lubricate mechanism with silicone spray
  • Check cable connection
  • Replace worn parts

Deflector Won’t Stay

Causes:

  • Friction mechanism worn
  • Pivot frozen
  • Spring broken

Fix: Adjust or replace friction mechanism.

Chute Clogs

Prevention:

  • Apply silicone spray or non-stick cooking spray
  • Clear snow before it compacts
  • Take smaller passes in wet snow

Clearing clogs:

  1. Stop engine
  2. Use clearing tool (never hands!)
  3. Clear chute and auger area
  4. Apply non-stick treatment
  5. Restart

Maintenance Schedule

Before Each Use

  • Check oil level
  • Verify fresh fuel
  • Inspect paddles visually
  • Test chute rotation
  • Check controls

Every 5 Hours

  • Check paddle wear
  • Inspect belt condition
  • Clear any debris

Every 25 Hours

  • Change engine oil
  • Inspect belt for wear
  • Check scraper bar adjustment
  • Lubricate chute mechanism

Pre-Season (Annually)

  • Fresh fuel
  • New spark plug
  • Inspect paddles thoroughly
  • Check scraper bar
  • Test all controls
  • Change oil

Storage (End of Season)

Fuel system:

  1. Run fuel dry or add stabilizer and run 5 minutes
  2. Drain carburetor bowl

Engine:

  1. Change oil
  2. Remove spark plug, add few drops of oil to cylinder
  3. Pull cord slowly to distribute

General:

  1. Clean entire unit
  2. Touch up paint if needed

Summary

The Troy-Bilt Squall is a solid entry-level snowblower for light snow clearing. Most problems trace back to old fuel causing carburetor issues or worn paddles reducing performance. Keep fresh fuel in the tank, replace paddles when worn and perform basic maintenance for reliable operation. Remember that single-stage machines are designed for lighter snow - don’t expect them to handle heavy or wet accumulations like a two-stage would.
