Small Engines (Lawn Mowers, etc.): 5 HP Tecumseh Sowblower engine, air leak, flow path
QuestionWhen I prime the engine, gas runs out all around and from in the carb. The flow of gas stops when I remove the priming tube from the carb. The engine runs, even when dumping gas. What's wrong?
AnswerHi Ken,
You will need to trace the primer flow path and look for a check valve or an air leak. If I remember, the primer pushes air into the carb, which draws fuel into the throat. I'm not familiar with your exact carb model so I can't pinpoint where to look. If that checks out but no difference, then I would look at the float and its' needle and seat for a problem but that would leak all the time if not correct.
Let me know how you make out.
