If I were to start up what you want, I would become a certified tech. Having a piece of paper goes a long ways when your advertising a business.
I would make sure I have all of the specialty tools
Gear puller
Case splitter
Compression tester
Spark tester
Piston ring tools
Voltmeter
Chain breaker
Chain press
Chain grinder (cause u ain’t gonna make any money sharpening chain by hand)
Mighty vac
For supplies I would absolutely have
This will be your bread and butter imo
Loops of chain
3/8 low pro in 050
.325 semi chisel in 050
3/8 full profile in 050, 058
I would carry Oregon and stihl chain initially
Spark plugs in the most common types.
Bar oil in winter and summer flavours
Two stroke oil, I would stick with one brand initially
—————
This is what you are gonna need for repairs occasionally
Fuel line in all sizes, a spool of each
Fuel / oil caps of various sizes, go aftermarket initially
For a business model
Focus on what you know best initially, sounds like saws from viewing your logo. Focus on a brand of saw that you are familiar with. Offer a warranty for your repair work
Your gonna need some connections to make this profitable. Imo I would advertise to your local logging companies in that area and or your local free care specialists.
Look em up and get their address. Talk to them in person, their office will probably reject solicitors. But if you come in and read their body language you can make things happen. If they look annoyed your there, don’t push it make it short and sweet.
“Just wanted to let you know, I fix small engine equipment, here’s my card if you are interested in quick and quality repair” leave the card and walk out.
If they seem receptive tell them the same thing but throw in some questions about who is repairing their equipment. Are they happy with them? If they are tell them that you are a good price and make a sacrifice in your rate to get their business.
Training in sales goes a long way here
I know it sounds dumb but after being a salesman for ten years long ago I can tell you it gives you a great skill. People skills, the art of perception, and the ability to close a sale without being pushy
That’s a long post but it made me think what I would do in your shoes.. something I may just do one day
