ignite, but motor
runs for a short
period of time.
1. A) Add fuel to tank.
B) Check fuel tank for bubbles
of water in bottom. If found,
remove fuel (see Storing,
Transporting, or Shipping, page
7). Clean tank and fuel filters
(see Fuel Filters, page 15). Fill
with clean fuel.
C) Remove wrong fuel (see
Storing, Transporting, or
Shipping, page 7). Clean tank
and fuel filters (see Fuel Filters,
page 15). Fill with correct fuel.
2. Replace nozzle (see Nozzle,
page 13).
3. Move heater to warmer place
until fuel flows freely.
4. Clean fuel filters (see Fuel
Filters, page 15).
5. Adjust pump pressure (see
Pump Pressure Adjustment,
page 14).
6. Connect spark plug wire to
spark plug.
7. A) Adjust electrode gap to
.075" (see Spark Plug, page 13).
B) Clean fuel from spark
plug with clean, soft cloth.
C) Replace plug if heavily
coated with carbon (see
Spark Plug, page 13).
D) Inspect plug for worn or
eroded electrodes. If found,
replace plug (see Spark Plug,
page 13).
8. Check electrical connections
and voltage to solenoid. If
good, replace solenoid valve.
9. Replace electronic ignitor.
