Small Engines (Lawn Mowers, etc.): Why is my Tecumseh 3.5 HP edger engine not running well?, fuel flow, good shape


Question
I've cleaned the entire engine except the crankcase, i've put clean gas in, and yet my engine will start but not stay running. When I start it it sounds strong then putters out rather quickly. I was thinking that maybe the problem was the timing but I have no idea how to adjust the engine or if that's even the problem. What do you think i need to do to fix it?

It is a Craftsmen Edger Model #:536 796536

Heres a link to my video of me starting it...

Answer
from what I saw on your video we can determine it has a good spark, and good compression. it the timing was a factor it would misfire when you sprayed the starting fluid rather than run. The problem is your not getting fuel to the engine, either it is the Carburetor needing a good rebuild, or a fuel filter (IF IT HAS ONE) or not getting fuel from the tank. Pull the line before the carb is there a good fuel flow? If yes, you need a carb rebuild (assuming the fuel is fresh and in good shape). If there is not a good flow of gas you will need to back track to the tank to find the blockage.............Tom
PS. Nice job with the video, others please take notice.
