I am looking for some ideas as to what may be wrong. I was running my H14 the other day and it was working great. Then I ran out of gas. It was typical changing of speed of engine for a minute or two then it stopped. I put gas in and it started right up. However since then it has stopped running after a few minutes (5-10) and refuses to restart. It seems to be flooded. After it sits a while, it will start and run for a while then the same thing happens. I have done this a few times.
I have a very new walbro carburetor, fuel filter and rebuilt the impulse pump. There is a new spark plug and air filter. I probably don't have 15 hours on them,
I don't expect a miracle cure through internet diagnosis but I bow to those with much more experience than me for thoughts as to what may be happening. The fuel filter was empty. Now it is about half full. I wondered if something happened to the fuel pump when it ran out of fuel. It is the original style walbro impulse which I rebuilt.
I will be going through the Tecumseh engine trouble shooting steps in the manual when I get a chance. I was hoping someone could point out a possible thing to check first.
