tuning the low speed needle on your nitro rc engine made easy 🏎️⛽️🚀💨

Описание: UNDERSTANDING THE TERMS RICH AND LEAN .
Your carburettor has screws that regulate how much air and fuel enter the engine together, the air/fuel mixture. An air/fuel mixture that is too
"rich" means there is too much fuel, and a mixture that is too "lean" means that there is not enough fuel for the given amount of air. When the mixture is too rich, performance will be sluggish (one symptom of this, is excessive amounts of smoke from the exhaust). There is also a potential to foul the glow plug when the mixture is too rich. When the mixture is too lean, there is not enough fuel to cool or lubricate the internal engine components, and damage to the engine and/or glow plug is almost certain .


Tuning Low Speed
The low-speed mixture affects how the engine will perform in the low to mid range rpms. Turning the low-speed needle clockwise will lean the mixture. As with the high-speed mixture, leaning the low-speed mixture increases performance.
HIGH SPEED ADJUSTMENT
Again, if the mixture here is set too lean, the engine may be starved for lubrication in the lowand mid-rpm ranges, thus causing overheating and excessive engine wear.Perform the following test to determine if the low speed mixture is set correctly. With the engine
IDLEwarm and running, allow it to idleADJUSTMENT
for approximately 15 seconds. Now quickly apply throttle and note the performance. If the engine bogs, accelerates erratically, and a large puff of blue smokes emitted, then the low speed mixture is too rich. Turn the low-speed screw clockwise 1/8 of a turn. If the engine speeds up
LOW SPEED ADJUSTMENT
for a moment then bogs, hesitates, or stalls, then the low speed mixture is too lean. Turn the screw counterclockwise 1/8 of a turn.
Adjust the mixture screws in 1/8 of a turn increments, wait 15 seconds, and retest after each change. Adjust for the best acceleration without the car
