Hello I have a doubt regarding this Novarossi Plus 4T this engine still continues to be a good choice for leisure and some regional competitions?

And here in Portugal to is a very good price € 246 offers:
Novarossi Plus4T
Carburetor glass of 6mm, 6.5mm and 7mm
Escape Novarossi NR-51018 EFRA 2084 (3 cameras / enhanced)

And I have a RB 92mm Long curve.

Good or bad???
