Chainsaw Repair

Looks like we have a few things in common LOL. I am in Alabama also and share the problem of having to give up some of the things I used to do.
I have worked on small engines for over fifty years and spinal problems, along with other problems, has forced me to "lighten up" at 69 years of age!
I work on chainsaws, trimmers and blowers as a longtime hobby, but the extra money is a blessing.
I only  buy to repair or keep in my collection, the higher end tools.
Cheaper tools are just that--made cheap. Parts sometimes cost more then the tool is worth or what people are willing to pay.
A close friend was given a Homelite chainsaw and wanted me to check it out. I cleaned the carburetor and it started on the second pull. I then discovered it was not oiling and the sprocket was a different size then the sprocket nose bar. I discovered this when I attempted to install the chain.
I told him the oil pump would need replacement and saw had to be nearly completely torn down to access.
With cost of pump and another sprocket or bar with my minimal labor, repair cost would be more then the cost of a new saw.
