So the black non limited coils are better for the saws?
The answer would be 'Yes' as well as 'No'.
It depends more on the user.
A person who knows his saw inside out might find the coils without speed limiters a better option, because he would know how and when to tune his saw.
But an average or new user is better off with the coil with a speed limiter, provided he avoids experimenting with the carb settings.
Huskys are sold in most countries as 'EPA' versions, which could also be read as lean burn with limited adjustments.
Asian markets still get the non-EPA versions.
