Im a newbie so please forgive me! I just dont know. I ordered a Raptor 30 with the upgrade and engine. The carburetor came in a separate bag. I put it in the engine but it slides around. I dont "think" that it is the way it is supposed to be. Could you all give me some tips on fixing this and maybe some things I should to set up my engine. Thanks everyone and be nice! By the way it is a tt engine! Thanks os.
