I have a Righetti Ridolfi World Formula Roller (New to Karting)

Make and model of chassis I have a Righetti Ridolfi World Formula Roller

I need help with is this for 4 Stroke or 2

What I’ve tried so far I have been told its not a particular great Chassis but ok for a starter.

Is it this one?

Extreme Kart is going to be a pretty econo-kart without much in the way of at-track support, but RR I’m sure makes plenty of stuff for it, so parts shouldn’t be an issue. It will be fine for a beginner.

Website there shows it’s a 4-stroke kart, presumably designed originally for the World Formula engine.
