Steve’s Small Engine Salon on YouTube has 630,000 subscribers, do the math. He is making a good/great living on money from videos alone. Why would he want to put up with crabby customers? Problem will be finding good equipment for content to make new videos.
No doubt that there are not as many people interested in any mechanical, etc. these days, not just small engines. They are too busy screwing around on the internet accomplishing zero.
These days many people want to either pay someone to fix whatever their issue is, or buy a new plastic, shiny product. Rarely do they try to tackle the problem themselves. The resourcefulness and independence is virtually gone.
