My lawn mower runs, but seems to be weak and suffering from a loss of power. In general, it is acting as though it is not getting enough air. I replaced the air filter, but the problem remains the same.
Unfortunately, there are about 5 or 6 things that can cause a loss of power and I am not enthusiastic about just randomly trying to fix things that aren't broken in the hopes that the problem will be randomly solved.
Is there any way I can do a test that will positively tell me why I have a loss of power without having to try random maybe-this-will-work type fixes?
Note that I am experienced taking apart carburetors, so if your answer involves instrumenting the carburetor in some way, I can do that.
Note that the mower is a Honda GCV160 which has an "auto choke" system. I suspect that may be the problem.
