7. Place a clean rag over the opening created by the
removal of the spark plug to make sure no dirt can
get into the combustion chamber.
8. Inspect the spark plug for:
• Cracked or chipped insulator
• Excessive wear
• Spark plug gap of 0.032 in. (0.80 mm).
If the spark plug fails any one of the
conditions listed above, replace the plug.
NOTICE
Only use the recommended spark plug (Torch
A5RTC or equivalent). See chart below. Using a non-
recommended spark plug could result in damage to
the engine.
9. Install the spark plug by carefully following the
steps outlined below:
a. Carefully insert the spark plug back into the
cylinder head. Hand-thread the spark plug until
it bottoms out.
b. Using the spark plug socket wrench provided,
turn the spark plug to ensure it is fully seated.
c. Replace the spark plug boot, making sure the
boot fully engages the spark plug’s tip.
d. Install the spark plug access cover.

CLEANING THE SPARK ARRESTOR
Check and clean the spark arrestor after every 100
hours of use or 6 months.
1. Stop the inverter and let it cool for several minutes
if running.
2. Move the inverter to a at, level surface.
3. Remove the screws holding the muer cover in
place.
4. Loosen the clamp holding the spark arrestor onto
the muer. (On iGen1200 unscrew the screw
holding in the internal spark arrestor).
5. Slide the spark arrestor band clamp o the spark
arrestor screen.
6. Pull the spark arrestor screen o the muer
exhaust pipe.
7. Using a wire brush, remove any dirt and debris that
may have collected on the spark arrestor screen.
8. If the spark arrestor screen shows signs of wear
(rips, tears or large openings in the screen), replace
the spark arrestor screen.
9. Install the spark arrestor components in the
following order:
a. Place spark arrestor screen over the muer
exhaust pipe. Push on the screen until it fully
bottoms out.
b. Place the spark arrestor band clamp over the
screen and tighten with a athead screwdriver
10. Replace the discharge gate.
CHECKING AND ADJUSTING VALVE LASH
CAUTION
Checking and adjusting valve lash
must be done when the engine is cold.
1. Remove the rocker arm cover and carefully remove
the gasket. If the gasket is torn or damaged, it must
be replaced.
2. Remove the spark plug so the engine can be
rotated more easily.
3. Rotate the engine to top dead center (TDC) of the
compression stroke. Looking through the spark
plug hole, the piston should be at the top.
4. Both the rocker arms should be loose at TDC on
the compression stroke. If they are not, rotate the
engine 360°.
