Why won't my Benchmark Lawn Mower engine start?

  There are several reasons why your Benchmark Lawn Mower engine might not start. It could be due to the choke being open (move the lever to close it unless the engine is warm), the engine switch being off (turn it on), or the lawn mower being out of fuel (refuel). Other potential causes include bad fuel (drain the tank and carburetor and refuel with fresh gasoline), faulty, fouled, or improperly gapped spark plugs (gap or replace them), or spark plugs wet with fuel (dry and reinstall them, then start the engine with the control lever in the FAST position). In some cases, the fuel filter may be clogged, or there could be a carburetor malfunction, ignition malfunction, or stuck valve (replace or repair faulty components as necessary).

  If your Benchmark Lawn Mower engine lacks power, it could be due to several reasons. The filter element(s) might be clogged, in which case you should clean or replace them. Another reason could be that you are out of fuel, so you should refuel. Also, bad fuel can cause this problem; if the engine was stored without treating or draining gasoline, or if it was refueled with bad gasoline, drain the fuel tank and carburetor and refuel with fresh gasoline. In some cases, the fuel filter may be clogged, or there could be a carburetor malfunction, ignition malfunction, or stuck valve; if so, replace or repair faulty components as necessary.

How to fix a Benchmark BCT24M engine that operates erratically?

  If your Benchmark Lawn Mower engine is operating erratically, it could be due to a defective spark plug (replace the spark plug). Another possible cause is an incorrect spark plug gap (set the gap between electrodes at 0.7 to 0.8 mm). A dirty air cleaner element could also be the reason (clean the air cleaner element).
