Have an old Kyosho 7.5 with a GX 21 engine, would the GS 21 sp be a direct replacement engine? Thank you

Yes, that should bolt in

could you link a replacement clutch for me as i need a new clutch and bell for this engine.
Asked by Max Rackstraw on 4th July 2020

The clutch depends on the car rather than the engine. But something like say AB-2300007 would be a good starting point
