      If your Makita Saw engine stops soon after starting, or the engine speed doesn't increase, it might be due to insufficient warm-up; perform a warm-up operation. Also, ensure the choke lever is set to “ON” once the engine is warmed up. A clogged fuel filter or a contaminated air cleaner can also cause these issues; clean them. For abnormal carburetor or drive system make request for inspection and maintenance.

      Deborah HillNov 22, 2025
      Your Makita Saw engine might not start due to several reasons. You may have failed to operate the primer pump (push 7 to 10 times), or the pulling speed of the starter rope is low (pull strongly). Other potential causes include lack of fuel (feed fuel), a clogged fuel filter (clean it), a broken fuel tube (straighten it), deteriorated fuel (replace with new fuel, recommended every month), excessive suction of fuel (set throttle lever from medium speed to high speed, and pull starter handle until engine starts. Once engine starts, cutting disc starts rotating. Pay full attention to cutting disc. If engine will not start still, remove spark plug, make electrode dry, and reassemble them as they originally are. Then, start as specified), a detached plug cap (attach securely), a contaminated sp...

      Phillip ReyesNov 23, 2025
      If your Makita Saw engine won't start, several factors could be at play. First, ensure you're operating the primer pump correctly by pushing it 7 to 10 times. A low pulling speed of the starter rope can also prevent ignition, so pull strongly. Check for a lack of fuel and replenish if necessary. Other potential issues include a clogged fuel filter (clean it), a broken or deteriorated fuel tube (straighten or replace it), or deteriorated fuel (replace it, ideally every month). Also, make sure the plug cap is securely attached and that the spark plug isn't contaminated (clean it) or has abnormal clearance (adjust it). If there is excessive suction of fuel, set throttle lever from medium speed to high speed, and pull starter handle until engine starts. Once engine starts, cutting disc starts ...
