i picked up a CRG chassis kart with a Radne engine ..but i dont have a clue what size engine it is or what mixture to run .. does any one know about these Radne engines ? ill take a photo and post.
I got the kart cheap and he told me it was a old Comer engine .. but i now know its not !
The Raket (Radne) engine was an 85cc engine intended for Cadet racers back in the late 1980s. It was fan cooled like a Comer, but it is not the same engine.It was never approved for use in Australia but was used as a junior class engine in several other countries, including IIRC New Zealand.
Your particular engine may not be that old Oztexs, but that is when we first saw them.
I think the engine is based on a Swedish chainsaw engine.
New Zealand ran them, believe they were replaced by the Mini Rok.
