I picked up a three year old Huskee LT-3800 Mower for $220. The seller thought it was dead but I was able to start it, so I bought it.
The first thing I had to to fix was the cable for engaging the blades. It is a 55" cable found on eBay for about $12. The replacement cable works great.
The next problem was that it would quit after one lap around the yard and would not restart for several minutes. There was a clog in the intake to the carburetor. I completely rebuilt the carburetor but all that needed to be done was to remove the clog with a jewelers screwdriver and then clean it up with a pipe cleaner. The red arrow shows where the problem was.
