What to do if my ICS 680GC Chainsaw will not start?
- N
  Nathan TaylorAug 17, 2025
  If your ICS Chainsaw won't start, there are several potential causes. First, clean, rebuild, or replace the recoil starter if it's dirty or broken. If the spark plug is soaked with fuel, dry it and expel excess fuel from the cylinder and crankcase. Ensure the switch is in the 'ON' position. Check and tighten ground wire connections, or replace the ground wire if necessary. Repair or replace the spark plug lead. Consider replacing the ignition coil. If the issue persists, it may be due to internal damage, requiring replacement of the piston and cylinder. Ensure you are using the correct fuel/oil mixture (25:1) and fresh fuel.

  The engine of your ICS Chainsaw could be overheating if the operator is overworking the saw, the carburetor mixture is too lean, the fuel/oil ratio is incorrect, the flywheel fins are clogged, the air deflector is missing, or the cylinder fins are clogged. Clean or replace the air filter. You may also need to replace the fuel filter, refer to the Carburetor Tuning section, repair or replace the fuel tank breather, or replace the pulse tube.

What to do if my ICS Chainsaw is difficult to start?
- K
  Kimberly BakerSep 2, 2025
  If your ICS Chainsaw is difficult to start, it might be due to a flooded engine. To resolve this, turn the ignition switch on, push the choke in, hold the throttle on full with your foot, and pull the starter cord in rapid succession until the engine starts. Another cause might be a fouled spark plug. In this case, remove the spark plug, clean it, and regap it to .020 in (.05 mm).

Why my ICS 680GC won't reach full RPM?
- E
  Erika VincentSep 5, 2025
  There are a few potential reasons why your ICS Chainsaw won't reach full RPM. It could be due to a dirty air filter or pre-filter. Another possibility is that the chain tension is too tight. The diamond chain should always be able to be pulled around the guidebar by hand, and it is normal for the diamond chain links to hang below the guidebar.

Why is the diamond chain breaking on my ICS Chainsaw?
- M
  Maria ThomasSep 12, 2025
  Diamond chain breakage in your ICS Chainsaw can occur due to several reasons. It may be caused by improper chain tension, inserting the saw into a slot narrower than the diamond chain segments, or not enough feed pressure while cutting. Avoid letting the saw bounce and chatter to prevent this issue.
