Gentle Readers,
How do I answer all these question? Well, maybe over thirty-five years of doing it face-to-face, over the phone or online might do that. I would be called "old school" since many of the brands I learned to work on had illutrated parts lists as the learning aid.
For engines I go to the sources:
Operator Manuals, Illustrated Parts Lists & Wiring Diagrams - Briggs & Stratton
Honda Engines
Kawasaki Engines & Power Products - Home Page
Kohler Engines: Owners & Service Manuals:
Manuals & Maintenance
Not all but answers most
And for equipment manufacturers I often go to:
Operator's Manuals for John Deere Equipment
Honda Power Equipment - Operator's and Owner's Manuals
PDF Manual Web Archive
Poulan Pro - Poulan - Weed Eater - McCulloch - User Manuals
Toro - Lawn Mowers, Zero Turn Mowers, Tractors, Snow Blowers
For reference purposes I often go to (order of preference):
Outdoor Power Equipment Information
Power equipment parts and accessories from Outdoor Distributors
K&T Parts House Lawn Mower Parts and Chain Saw & Trimmer Parts
