Right on! the DLE 55cc is VERY powerful... I actually checked where the factory had their settings on the engine compared to the manual and they were very close but I did put the low end needle @ 1 1/4 out and the high end @ 1 1/2 out and it fired right up, idled great and had good transition... The only thing I have encountered negatively is the vibrations... The vibes @ idle feel normal but throughout the whole rpm range there are bad vibrations... Some vibes are expected but these are NOT normal...
