Learn how to bypass the Victa G4 carburetor ignition with a simple on off switch.
- Phillips Head Screwdriver
- Wire Trimmers & Cutters
- Electrical Tape
- Cable Ties
- Solder & Soldering Iron (optional)
- Spark Plug Tool
- On/Off Switch & Wiring
Remove the top cover and place it aside.
Twist the carburetor off and pull out one of the ignition wires, the black one is usually easiest.
If your lawn mower previously had no spark (click here to watch video on testing spark plug), and if it now has a spark it means your G4 carburetor is worn out and the ignition wires are contacting. If you still have no spark your problem is likely the ignition coil, which we will feature in future video.
If your problem is the carburetor ignition, we can bypass it with a switch, making it much more reliable. To do this remove the second wire from the carburetor as shown in the video.
Next, strip the wires and connect the extra wiring you have prepared. Then mount your switch and connect it to the wires, it will only matter which wire is connected to which if you have a toggle switch – reversing the wires will reverse the on/off parts of the switch.
Create a hole in the cover of the lawn mower for the switch to mount to. Thread the wires through this hole, then connect them to the on/off switch and tighten the switch to the cover.
Once the switch is installed you can replace the black rubber cover on the carburetor to stop dirt & excess air being sucked in.
