Re: DLE 20 Tuning

Your YouTube video doesn't work as you have marked it private.

Remember one little tweak at a time and a low end adjustment also effects the high end and vice versus.

Great running engine.

Re: DLE 20 Tuning

The low end is all about the transition. If it stumbles while revving it is rich. If it bogs or dies the low end is lean. Don't baby it. Bang the throttle to the stop. Once close let the engine idle for a minute or two and bang it full. If correct it will rev instantly, if it stumbles with some smoke it is still a hair rich on the low.

The high is peak. As you lean the high end you will hit a plateau more so than a peak. Keep the high end on the rich side of peak.

The low end affects the entire range while the high only affects the high end.
If you adjust the high you can leave the low alone. If you adjust the low end you will need to tweak the high end. Richer low end will require a leaner high end and a leaner low end will require a richer high end. Once close just turn them the width of the blade.

Also I like to mount subway straws over the needles and out to a hole in the cowl. The straws hold the screw driver on the needle even during full throttle, makes tuning the high end very easy and quick. Round the end of the flat screwdriver to make it easier to turn the needle at an angle if need be.
