| How
do they work... |
|
Glow
plugs work because of a catalytic reaction between the methanol
based fuel and the platinum element. Without this fuel or the
platinum wire the glow plug would not continue to glow when
the 1 1/2 volt booster battery is removed. See also Fuels
and Compression Ratio

| What
glow plug should I use for aircraft engines? |
|
For regular
use in engines equipped with mufflers a standard K&B 1L
#7311 plug is good. In older engines a R/C K&B 4520
plug may produce a better idle. If you have trouble with short
plug life a K&B 7310 heavy duty plug may be the best. |
|
| What
glow plug should I use for marine engines? |
|
If
you are using less than 25% nitro content fuel a standard K&B
1L #7311 plug is good. For 25% and higher content
nitro fuel a K&B 7300 high performance plug is recommended.
Note: Early K&B 3.5 outboard and marine engines used short
reach plugs and later changed to long reach. Plug thread should
not extend past the treads inside the head combustion chamber. |

| What
glow plug should I use for auto engines? |
|
Check to
see if your engine uses a long or short plug. We recommend a
K&B 1L #7311 long or a K&B 1S #7321 short |

| What
glow plug should I use in 4 stroke engines |
|
The K&B
4444 or the Fuji type F plugs work perfect in all poppet valve
four stroke engines. THESE ARE NOT FOR HP VT ENGINES |
|
| What
glow plug should I use in HP VT 4 stroke engines |
|
The K&B
7311 works perfect in HP VT four stroke engines. Don't
use an R/C, 4 cycle, miracle or any other plugs that have anything
extending from the end. These plugs can hit and destroy the
rotary valve. Note early VT's 21's use a standard short plug
like the K&B 1S 7321. You can identify the early version
by the rotating valve, early used a bronze valve in a chromed
sleeve, all later engines used a chrome valve in a bronze sleeve. |
