well I've now learn' t not to put a .46 nitro engine in a 1/8 buggy so i have listen to u guys and have purchased a brand new mac .28 6 port engine and got it going. and so if its idling should it make lots off blue smoke when I'm not even reeving it. is it because its to rich or to lean and when i do give it some gas it goes woooooo and dies:bow::bow::bow:
