Is it the Starter or the Engine?

If you have an Electric Start Generator, and cannot get it to start, the first thing to diagnose is whether it is your Electric Start system or the Engine at fault. If you attempt an electric start, and it is unsuccessful, it’s worth trying to manually start the Generator (if you have a Recoil). If it will start manually it’s likely a problem in the Electric Start system – In this case, it would be a good idea to contact our Engineers below by beginning an engineering ticket (bottom of the page).

If the starter spins but the engine does not fire, check the battery voltage, it may be too low to spin the engine fast enough. If the battery voltage is ok, then the problem is engine related and most likely a fuel problem.

If you suspect the problem is engine related Click this link to go to our Engine Problems section.


If you find that the unit is backfiring, or kicking back on the Recoil, the Valve clearances probably need adjusting. We list all the Valve settings on our website under the Valves and/or Cylinder Head Parts listings. Please see our Parts System to look up the clearance settings for your particular machine, or contact us below.

If you believe you have any other Electric Start problems, please contact our Engineers below.
