Our engine is brand new. It will start and then die again rite away. Now the engine will not start at all and pops how do we fix it or get it to run?

Asked by: Owen69
Check to make sure you have fresh fuel. Fuel can go stale in as little as 2 weeks and cause the passageways in the carburetor to clog. You will want to change the fuel and spray the carburetor with carb and choke cleaner.
