How to tell if your glow plug is bad
The glow plugs on the market today are designed
to provide good service to the user and may last a long
time or a short time, all dependent upon the way you
choose to operate your engine.
Physical indications that you might need to
change the glow plug are:
1. Twisted or mangled glow plug element (usually
caused by too high a compression ratio).
2. Small “bumps” are attached to the glow plug
element. This will generally be most noticeable
during the break-in process. These are actually
tiny pieces of aluminum that have attached to the
element and these will severely hinder the operation
of the glow plug.
3. The glow plug element is no longer shiny but is dull,
almost a white powder color. (This just comes with
age and is a by-product of the catalytic reaction.
The shinier the wire, the better the catalytic reaction
can be).
Operating indications that you need to change
your glow plug are:
1. The glow element will not light with a charged glow
igniter. This indicates that there is a physical short
or breakage in the element wire itself.
2. Glow plug lights but the engine will not continue
running once the battery is disconnected. (This is
usually an indication of the microscopic particles
we discussed earlier).
3. Glow plug lights, engine runs but there is a
perceptible loss of rpm at full throttle when the
battery is disconnected. This is a typical indication
that the white powder residue is building to the
point that the catalytic reaction of the glow plug is
no longer anywhere close to being optimum.
Troubleshooting Guide
Engine Won’t Fire
• Glow starter not charged
- Charge glow starter
• Glow plug burnt out
- Replace glow plug
• No fuel is getting to the carburetor
- Check tank, fuel lines reversed
• The starter is reversed
- Reverse the polarity on the starter cables
Engine Quits Repeatedly
• Needles need adjusting
- See adjustment procedure
• Bad or old fuel
- Replace with fresh fuel
• Worn out glow plug
- Replace with new HAN3006 super plug
Engine Runs Inconsistently
• Hole in fuel line
- Replace fuel line
• Bad or old fuel
- Replace with fresh fuel
Maintenance
After each flying session:
1. Fully drain the fuel from the tank.
2. Start the engine and run it until the fuel is
completely run out of the engine.
3. Try starting the engine three more times or until
it will no longer fire. This gets all the fuel out of
the engine.
If the engine will not be used within 10 days, several
drops (about 10) of after run oil (Evolution Engine's
Blue Block Rust Inhibitor) should be applied into the
carburetor and the engine should be turned over for
a few seconds with the starter. This will prevent rust
and corrosion.
