Seasonal Small Engine Maintenance Tips | Terry Roth Winnipeg
Seasonal Tips for Keeping Your Small Engine in Peak Condition
By Terry Roth, General Manager, Winnipeg Mobile Lawnmower Tune-Up
After 20 years of mobile small engine repair across Winnipeg, I've learned that the difference between equipment that runs reliably for decades and equipment that constantly breaks down isn't the brand name or the price paid – it's how well owners understand and adapt to our unique Prairie seasons. Manitoba's extreme seasonal changes create maintenance challenges that generic owner's manuals never address.
From -40°C January mornings to +35°C July afternoons, with spring floods, summer dust storms, and early fall freezes, our small engines face conditions that would challenge equipment twice their size. Having serviced over 80,000 pieces of equipment through every conceivable Prairie weather pattern, Gail and I have developed seasonal maintenance strategies that actually work in our climate.
Here's your complete guide to seasonal small engine care that will keep your equipment running reliably through every Manitoba season, year after year.
Understanding Prairie Seasons: Why Generic Advice Doesn't Work Here
The Unique Challenge of Manitoba Weather
Temperature Extremes: Our 75°C temperature range (from -40°C to +35°C) creates expansion, contraction, and thermal stress that temperate climate equipment never experiences.
Humidity Swings: From bone-dry winter air to humid summer conditions, moisture content changes constantly affect fuel systems, air filtration, and metal components.
Seasonal Transitions: Rapid weather changes – like March thaws followed by April blizzards – create conditions that standard maintenance schedules don't account for.
Extended Storage Periods: Equipment sits unused for 6-8 months annually, creating storage-related problems that milder climates never face.
Why Seasonal Adaptation Matters
Generic Maintenance Schedules Fail: Following manufacturer recommendations designed for temperate climates leads to premature failures in Prairie conditions.
Seasonal Damage Accumulates: Problems that develop during one season often don't show symptoms until the next, making diagnosis difficult.
Prevention vs. Reaction: Seasonal maintenance prevents problems rather than just fixing them after they occur.
Equipment Longevity: Proper seasonal care can double or triple equipment lifespan in our harsh conditions.
Spring: The Critical Season for Small Engine Success
March-April: Pre-Season Preparation
Spring preparation is the most important maintenance period of the year. Equipment that's properly prepared in March and April runs reliably all season. Equipment that isn't often fails during the first heat wave or heavy use period.
The Spring Startup Checklist That Actually Works:
1. Fuel System Overhaul
Drain All Old Fuel: Even fuel stored with stabilizer should be replaced after 4+ months
Fresh Premium Fuel: Use 91+ octane fuel with ethanol treatment for first tank
Fuel Filter Replacement: Install new fuel filter before adding fresh fuel
Fuel Line Inspection: Check for cracks, softening, or ethanol damage
Carburetor Assessment: Look for fuel stains, leaks, or varnish buildup
Why This Matters: 60% of our spring service calls are fuel-related problems that could have been prevented with proper fuel system preparation.
2. Lubrication System Service
Complete Oil Change: Fresh oil, proper viscosity for spring temperatures
Oil Filter Replacement: If equipped, always change with oil
Grease All Fittings: Every grease fitting gets fresh grease
Cable Lubrication: All control cables get white lithium grease treatment
Moving Parts Service: Pivot points, wheel bearings, deck hangers
Prairie Specific: Our temperature swings require oil that can handle both cool spring mornings and hot summer afternoons.
3. Air Filtration Overhaul
New Air Filter: Start season with fresh filter, not cleaned old one
Pre-Filter Cleaning: Foam pre-filters get washed and re-oiled
Air Box Inspection: Check for cracks, loose connections, or mouse damage
Intake System Check: Ensure no debris in intake tract
Dust Reality: Prairie springs are incredibly dusty. Starting with a fresh filter is essential.
4. Ignition System Refresh
New Spark Plug: Fresh plug gapped to specifications
Ignition Wire Inspection: Check for cracks, corrosion, or damage
Magneto Gap Check: Ensure proper clearance between magneto and flywheel
Safety Switch Testing: All safety switches must function properly
5. Cutting System Preparation
