Why Powersmart Snow Blower engine fails to start but cranks over?

  If the engine of your Powersmart Snow Blower fails to start but cranks over, there are several potential causes. It could be due to a disconnected spark plug wire (connect it), a faulty spark plug (clean, adjust the gap, or replace it), or the engine being flooded with fuel (discontinue choke or primer use and clean or replace the spark plug). Other possible reasons include the safety key not being fully inserted (insert it), the choke not being in the START position (move it to START, then slowly to RUN), incorrect or stale fuel (empty and clean the fuel tank and carburetor, then refill with fresh gasoline), a blocked fuel system (clean it), or the extension cord not properly attached to the electric starter terminal (re-insert it).

  If your Powersmart Snow Blower engine runs erratically, stalls, or seems low on power, the issue could stem from several causes. You might have incorrect, old, or stale fuel (empty and clean the fuel tank and carburetor, then refill with fresh, clean gasoline). Alternatively, the fuel system or line could be blocked or clogged (clean it), the carburetor may need cleaning (clean the fuel system and carburetor), the spark plug wire could be loose (connect and tighten it), or the spark plug could be faulty (clean, adjust the gap, or replace it). Also, check if the engine oil is overfilled (drain it to the proper level) or low/empty (add oil).

  If the electric starter on your Powersmart Snow Blower will not crank the engine, it could be due to a few reasons: there may be no power from the power supply or a tripped breaker (check the extension cord attached to the power supply), the extension cord wire gauge may be too small or the cord is too long (use a proper rated and length extension cord), or the CHOKE is in the ON or partial ON position (move the CHOKE lever to RUN).

  If there is no forward or reverse drive movement when the drive handle is engaged on your Powersmart Snow Blower, the drive belt might be loose or damaged (check the drive belt tension pulley for damage or incorrect tension, repair as necessary, or replace the drive belt). Alternatively, the friction drive wheel could be worn or damaged (replace it), wet or slipping (allow the snow blower to dry and warm up or adjust the drive cable tension), or the wheel to axle pins could be broken or missing (replace the pins attaching the wheels to the axle).

What to do if Powersmart MB7109A Snow Blower drive speed control stuck in gear?
- M
  Michael AllenSep 3, 2025
  If the drive speed control on your Powersmart Snow Blower is stuck in gear or won’t change gears, it could be due to a speed control lever that is loose or damaged, not moving the speed control cables (check the speed control lever and cables for damage or loose or missing parts, repair or replace parts as needed, ensure pivot stud spring tension is correct, adjust pivot nut spring tension as needed). Another possibility is that the speed control cables are loose, damaged, or binding (repair, adjust, or replace as necessary).

  If the drive speed control on your Powersmart Snow Blower allows only one direction, the speed control cables may be misadjusted, loose, damaged, or binding. To resolve this, check the speed control lever and cables for damage or loose or missing parts, repair or replace parts as needed, and adjust the drive speed control cables.
