CARBURETOR ADJUSTMENT
NOTE
If clean fresh gasoline with Dyna-Fog® Fuel Stabilizer additive is used, the
Carburetor will almost never require servicing. Usually most operational problems
involve carbon build-up, weak spark, or excessive priming causing the engine to
flood. AlI of these possibilities should be checked before working on Carburetor.
An out of adjustment Carburetor will cause the following symptoms. Note that all of
these can also be caused by a weak battery and/or carbon build-up.
Symptom: #1
Machine is hard to start (too much gasoline.)
Cause
:
1. Inlet Needle Valve wedged open.
2. Fuel Needle set too far open.
3. Metering Lever set too far out.
Symptom: #2
Machine is hard to start (not enough gasoline.)
Cause:
1. Carburetor is clogged.
2. Fuel needle stuck to its seat.
3. Metering lever set too far in.
Symptom: #3
Machine runs but dies when beginning to fog.
Cause
:
1. Fuel-air mixture is too lean or too rich.
2. ON/OFF linkage not fully rotating butterfly plate in carburetor (Fig. 7, Item 8).
ADJUSTING THE FUEL NEEDLE
The engine must be running in order to adjust the Fuel Needle.
If the engine will not run and the Fuel Needle is set between ½ -1 turn out, the Fuel Needle setting
is not likely to be the problem.
If the engine will not run and the Fuel Needle is not set between ½ - 1 turn out, set the Needle to
this setting. The machine should start in this range.
Once the machine is running proceed as follows:
1. With Fuel Oil or Flushing Solution in the Formulation Tank, move the machine where it can be
fogged briefly with safety.
2. Set the Formulation Metering Valve to "10" and start the machine.
CAUTION
If the machine is running too lean or too rich the next step may cause the
engine to stop and a small amount of flame may exit the engine discharge.
NOTE
A Pulse Jet Engine which has lean fuel-air mixture will not carry fog. A Pulse Jet
Engine, if running rich will run rough or sputter frequently.
