Its a very very old Novarossi engine. Almost 5-6 years old. It was top of the line back then. Its similar to a NSR.
I believe that for 30%, you should use 0.5mm shimms. And a #7 glow plug. I remember those engines screaming from 250 to 280. But this will all depend on the pipe you use, weather and fuel.
