Has anyone bought this motor in here?

Well i just ordered it and starting to break it in... there's no manual that came with it... but for $55.99 it's worth trying it out than my stock .15 ae that came with my ntc3+...

Here's the spec:

- Side Exhaust
- Displacement: 2.95cc/ 0.18 cu.in
- Bore: 16.50 mm
- Stroke: 14.00 mm
- Practical R.P.M.: 4000 - 40,000
- Output: 2.1PS/32,000 R.P.M.
- Weight: 258g

The power that is put out by the manufacturer seems a bit odd... 2.1PS that's 2.0 HP?

It almost have the same stats of the PICCO .18 motor... except that the bore is .50mm wider...

If anyone has this or heard of this engine let me know... i can't seems to get it to idle to the point that your car is not moving.. i've already tweaked around the mixture... can't find luck... ive gone thru 2 tanks already...
