I've got one, sloppy casts, dents and scratches, and typically very low end parts common with "house brands" (and they're 66cc if ya didn't already know)
Get a Grubee, they're pretty much the same price yet better carb and other goodies. The casting is
much nicer too
FYI, it seems that A: the ugliest motors are the ones chosen for paint and B: the paint jobs themselves are hurried and sloppy... So my advice is to get a unpainted Grubee and paint it yourself, taking your time to apply light coats with a quality engine paint.
You'll end up with a much nicer job than the drippy gooberpile I got in the mail lol
Yet if you already have one - fret not, it seems to be running fine (after about 300mi lol) I just need replace the carb. I could just rejet the one I have, but I figured why bother when there's much nicer ones with an actual fuel/air mix screw for a whopping $50
