hey guys, im really new to this. i got a buggy with a novarossi engine in it, but as i dont kno nething about it i dont know which engine it is. i pulled the engine apart a few days ago because it had been sitting for too many years and the engine felt seized. i found on the piston, dents where it had been detonating and a tiny bit of play between the crank and the rod. ive lookd on the novarossi site for sleeves, pistions, rods n bearings but i cant even tell wot engine it is. as far as i can tell its a nova RX21 3.5, thats all that is writen on it. i was wonderin if u could tell me if its worth while rebuilding it(if i can) and if i can get the stuff in melbourne. thanks alot, James
