  Kenneth, just wanted to praise you for your book. It has really helped me get started with my nitro car.

I must say that as an amateur it is simply a must to have your book, and it is incredibly thorough. There are some great pictures where one can really see what is going on... thank you so much for dedicating so much of your time to it.

 My review of the book is that it is generally good and can definately be recommended to amateur drivers.
The value of the book to an amateur driver in relation to its price = 10 on a scale from 1 to 10

 Hi Kenneth. Why on earth did I not have this book when I started driving nitro cars? Great job, thank you so much.

How to adjust your nitro engine

When you have to adjust your nitro engine it is important that you have some knowledge of what to do before you get into it. It is at this point of adjusting the engine that most people throw their hands up in the air and give up driving nitro cars. It is a pity, because the nitro engine is really harmless and very simple to deal with, once people have understood its principles beforehand.

Let me clarify that there is no right or wrong way to adjust a nitro engine as long as the way you do it works for you. Whether you choose to adjust your engine by following the example I have made for you, or by following the advice given to you by the supplier, you still need to understand the principles and factors involved.

There are 3 screws we works with, when we refer to adjusting:

- Bottom screw (Low-end) Regulates the conditions for fuel supply in the area within 0-30% of engine speed.

- Top screw (High-end) Regulates the condition for fuel supply in the area within 30-100% of engine speed.

- Idle screw, which forms the end stop for the gas throttle-valve and dictates the idle speed.

When we adjust the bottom and top screw we do it only 1/8 of a turn at a time, no more.

Is your current adjustment not working and you do not know the suppliers advice for it, you can normally get away with just turning the top and bottom screws 2-3 turns out from the bottom position, but it can vary from engine to engine.

Before you can adjust your engine you need to always make sure that the working temperature is right. That is, start the engine and warm it up before you start adjusting anything.

If you adjust more then half a turn out on the bottom screw, it will be necessary to adjust the top screw in 
(and vice versa)

Adjusting according to weather and temperature
A perfect combustion in the engine occurs when the relationship between fuel and oxygen molecules are perfectly mixed. The problem is that air does not always have the same number of oxygen molecules in it. It actually depends on the humidity in the air and the temperature.


You can learn about this and much more in Nitrobook.
