Hey everyone. I have an old (5+ years, pre fancy new engines) nitro rustler, that I want to give a new engine. It had the Pro .15, but it got some .16 (forget brand) and I was thinking about getting a nice new O.S. or associated engine. It has to have a rotary carb, and a short crank I believe? What would you guys recommend for it for under $125? Oh, pull-start.

I'm leaning towards this one. http://www3.towerhobbies.com/cgi-bin...?&I=LXGGP8&P=0
