Anything that has a gasoline engine will require the knowledge and
ability to perform minor adjustments and repairs. These seem to
be beyond your abilities. Generally speaking, electric outdoor
products do not have the power of the internal combustion units.
If you buy something with a gasoline engine, look for a Honda
engine. They cost a bunch more and will usually need to go to a
professional when they malfunction, but the malfunctions seem to
be further apart. It seems that Tecumseh and Briggs units don't
work well for you.
