Most that I've seen have 2-3 minutes of a silly opening act(that you can fast forward through) followed by a lot of solid content(20 minutes-90 minutes depending on what it is) and some corny humor interspaced. A lot of his "humor" is the whole big teeth, etc get-up along with his own butchered but humorous names for different things("breaks and scrap'em" for example).
Aside from day-to-day repairs he'll find interesting stuff in his boneyard and bring it back to life. As he's doing it, he's great about providing sources and PNs for things he's replacing. I happened across it by accident watching a resurrection of a Lawn Boy D600-powered mower. He sold and serviced Lawn Boys back in the day so he has lots of NOS parts, factory tools, etc but also tons of experience with actually fixing them. In that one he re-rings the engine and does other things I've not seen videoed elsewhere like setting up the centrifugal governor correctly.
The channel is Taryl Fixes All. Again, expect the stupid stuff but on the whole I find the quality of the content far outweighs seeing a stupid skit at the beginning or hearing him talk about cleaning a "muffkin"(muffler).
