um its a weedeater engine, i dont know what its made of this is the DIY forum and i thought that means absolutely no kits right, well, so, yeah, okay, so i think it might be aluminum though because of what it looks like, when i get a chance i'll take pics because im not home right now but that welding plate idea is a good idea so i'll cut me out some brackets weld them onto the frame and bolt it through if i can get ahold of a welder in time i also wanted to know where a welding shop would be in maryland aside from the school that i go to where i can do my own projects at the school. i know how to mig weld stick weld and use acetelyne(however you spell it) to cut steel. or some one could tell me how to mount an engine, make a jackshaft well do just about everything without welding at all just to let you know i completely took the engine out of the trimmer so whats on it is the carb muffler and clutch i'm gonna use a electric drill to start the engine till i can find a better way to start it i also need to clean the carb i know the engine works because i put a small amount of 2 stroke gas straight in the carb and it started okay for a faew seconds the only problem is the carb also i would like to know how to kill the engine i still have tthe kill switch i just dont know where i would put it on the bike to short out the engine im practically building everything from the ground up so please help also if this drags on too long i will inevitably get 150 dollars for x-mas so i'll buy me an engine kit but it would be a waste because i woulndn't be able to experience actually building everything
