Ok guys, i see a lot of people are into nitro rc. Seeing as i have no life, i thought id write up a guide for all you nitro guys ;p
Too Lean
Here are some symptoms of an engine that is running too lean:
1. Dies or "flames out" at full throttle.
2. The glow plug wire or "element" turns white.
3. A drop of water or spit on the engine heat immediately sizzles. Too hot.
4. Dies while just idling.
5. Dies while accelerating from idle. Note this can also be caused by a rich engine.
Too Rich
Here are some symptoms of an engine that is running too rich:
1. A lot of blue smoke from the exhaust pipe.
2. A lot of unburned fuel exiting the exhaust pipe.
3. Idles properly, but bogs down an dies when the throttle is full applied.
4. Never reaches full top speed.
5. Engine temperature is too cold (e.g. below 200 F degrees)
Glow Plugs
Glow plugs are very important to the performance of your engine. You can also read your glow plugs to determine if you are running too rich or too lean.
A brand new glow plug has a wire or filament that is shiny. If after running the wire is still shiny and the bottom of the plug is wet, then you are running too rich. You are probably getting only 85% of the maximum engine power.
If the wire turns starts to turn gray, and the bottom of the filament is slightly wet, then you are almost near the peak engine power.
Once you have a gray wire, and the bottom of the plug is dry, you are at 100% maximum power.
Once the glow plug wire starts to distort, you have exceeded the maximum power and are running too lean. Adjust to a slightly rich setting.
Hot plugs are used for hot summer days, while cold plugs are designed for cold "winter" days.
Thats only some of what i wrote into a word doc, so if anybody finds this helpful ill put up the rest if you'd like. Cheers!
