How to change 6.5HGJAE-3554J propane generator spark plugs

Hello, my name is ***** ***** I am going to assist you with this.

Changing plugs on this unit is not difficult.

Remove the plug wires from the spark plugs.

Use the proper size spark plug socket (13/16"), and remove the old plugs.

Gap the new plugs to .025", and screw them in. Torque them to 18 - 25 ft-lbs.

Snap the plug wires back on the plugs.

Sorry I do not know where the spark plugs are. It is ok. I had a mechanic look at it today.

The #2 (right hand) spark plug is located directly behind the right valve cover.

The #1 (left hand) plug is located behind the left valve cover, which is behind the air intake box. You can not see it without a mirror, but you can easily feel it with your hand.
