One of the best running .46's I have is an Evo .46 NT that I got as a freebie...[8D]
A guy gave it to me after getting fustrated w/ it...was ready to pitch it in the trash...I told him "throw it my way"
The limiters on the carb can be a PIA to some...and I have gotten rid of them on all the Evo glow 2 strokes that I own (3 of them...a .455 Alpha, 2 .46's )

They are basically good engines, and some have carb "issues" but for the most part, the ones I have and have seen are a good value and are good performers.
