Engine Tuning Tips (Part 1)

Engine is the heart and hub of any machine. Its functioning needs to be understood very clearly before touching any of its part. A basic understanding of fundamentals would help in better tuning of the engine and in turn engine would give maximum performance and also shall have better longevity.

Glow engines can prove difficult to tune, this is the most prevalent myth. With a little bit of know-how, tuning a glow engine can really be a simple, pain-free process. People that don’t properly understand the basics can easily become frustrated by what should be a simple, straightforward process.

Let us assume that everything else in the car is in shape and the engine is not giving any start up problems. Then refer to the instruction manual which should specify the instructions to set up your aperture size to minimum. This is important because if your engine cannot get enough air or gas flow then It would not run properly. A clockwise rotation opens the aperture and increases the idle RPMs, a counterclockwise slows it down.

Next would come to tuning of low-end mixture valve. This is done before the high-end (main needle) adjustment because an improperly adjusted low-end can affect the high-end performance. Like most mixture valves, clockwise rotation will “lean” the mixture and a counterclockwise will “richen” the mixture. Allow the engine to warm up completely, and then allow it to idle, uninterrupted for one full minute. This would determine whether the low-end mixture requires any tuning or not. If the engine runs continuously then the mixture needs not any adjustments but this means that the mixture is either too rich or too-low. Check out on that.
