new to 2 strokes, are they supossed to come down to idle slowly, just seems like when you rev it up it comes down slowly and different every time ? sorry but never had a 2 stroke before. runs great though.

 

Yep it's running right all twostrokes rev up high and and once gas is let off they come down to an idle slow.

 

If it is too slow though it is very vindictive of a air leak somewhere. I had this problem twice, once was the seal between the reed box and the second was a cracked engine case that I didn't notice when I rebuilt the bottom end. They really shouldn't come down to an idle much slower than a 4 stroke, they will a little but if you are talking about sitting high idle for a couple of seconds then drop to an idle I would bet on a air leak.
