Why does my Mantis engine lack power?

  Tony Burnett DDSAug 21, 2025
  If your Mantis Tiller engine lacks power, the air filter may be clogged and needs cleaning or replacement. The carburetor might be out of adjustment. Another possibility is a clogged exhaust, clogged exhaust ports, or a clogged spark arrestor. Poor compression could also be the cause. To resolve these issues, clean the carbon from the exhaust. Remove the exhaust, rotate the engine until the piston is at the top of the cylinder, and carefully remove all carbon from the exhaust ports with a wooden scraper or blunt tool, being cautious not to scratch the piston or cylinder walls. Blow out any loose carbon with compressed air, then reinstall the exhaust and gasket. Clean the spark arrestor Contact your local authorised dealer.
