need help for senior project

ok i need help my son tony ( the one that works at mcd's) needs a small engine project for school so he can graduate. if anyone has anything that might work as long as it isn't a lawn mower, weed wacker, chain saw or anything like that i would appreciate you letting me buy it off you or letting him work on it for his senior project.
thanks
mel and tony

so NO mower, weedwacker etc?

yeppers none of that easy stuff but he can and will fix them for you if you want

what about a t case or a tranny?

not sure I follow you, if you consider lawn mowers to small of a motor, are you looking for a small car motor? Keep in mind that their is a huge differance between a 32cc chainsaw motor and a 30 hp lawnmower motor. But not that much difference between a 30 hp motor and 125 hp motor. Its just a matter of how many cylinders and a few more bolts and wires.

ummmm from what i understand it can be like a go cart, 4 wheeler , cycle or something along that line. ummm i am just the mom lol i have no clue the difference between those engines. but ty all for asking and seeing if there is anything he can do. he could even make a hoverround or jazzie motorrized as long as it works when he is done.

oh okay, you mean no 2 stroke motors (aka engines that need oil mixed in the gas) just 4 stroke motors (which take straight gas).

all i can say is thank you and tony passed his senior project he has to write a report and ummm put a brake on it lol cause the teacher said he would kill himself if he doesn't. rob i owe you big time and many thanks you helped me out so much with this. all it was is dirty plugs and the carb needed cleaned ohh and tony said gas.
