  If your Troy-Bilt Blower engine won't start, several factors could be at play. First, ensure the fuel tank isn't empty by filling it with properly-mixed fuel. If that's not the issue, try pressing the primer bulb 10 times, or until fuel becomes visible. If the engine is flooded, move the choke lever to the RUN position, squeeze the throttle, and pull the starter rope. Old or improperly mixed fuel can also be a culprit; in this case, drain the tank and add fresh fuel. Lastly, a fouled spark plug could be the cause, so consider replacing it.
