4020 Gas Starting Problems

Stillman Mike · May 31, 2010

I have a gas 4020 that runs very well but is difficult to start, especially in warm weather. The engine cranks for 15-20 seconds puffing black smoke intermittently and then finally starts. When it's run for a minute or so and shut down, it will start immediately. The starter has plenty of starting torque and I recently tuned up the engine but did not adjust the timing. The fuel filter is new but I have never worked on the carb or replaced the fuel pump. Any help would be appreciated

try turning fuel off when it sits probably bad neddle and seat over filling bowl after time

This sounds reasonable. A leaking valve would likely cause the rich mixture I"m seeing. I"ll give it a try. Thanks a bunch.

I tried closing the shutoff valve after shutting down the tractor. After sitting for a day or so, the tractor started right up. Hasn't worked like this for years. Thanks for the tip.
