Default project motor.

just got a free 5 horse briggs fun power go kart motor. and whowee! its gonna be a fun build. im taking it down to bare block and starting from there. it wasnt running when i got it, but it will be when im done here. there is some stuff that will need to be replaced (the flywheel. yucky rust!, might just soak in clr or something insted). once i get it running with stock parts, im going to then work on performance stuff. if i can get this fast enough im just going to use this insted of a dirt bike motor. the only things left in the block is the piston, crank and valves. i dont have the carb off yet cuz it has torx bolts... which i have no torx drivers(that i can find).

so what do yall think? i think its worth working on. do you?

That doesnt look bad at all, how much compression does it have? Put in a carb kit if you cant get it running, as for the fly wheel, just sand the magnet part down and it should work, i did that for a motor i found in snow bank in the spring.

i dont know about compression yet, looks good but i had my thumb over the exhaust port and heard hissing wen i rotated it. and with my thumb over the spark plug hole. it needs gaskets too. carb looks good at the moment. gonna soak it in parts cleaner/carb cleaner. i need to wash everything too. its dirtyyyy. they diddnt change the oil at all. i bet that was why it diddnt run.

looks good, exhaust sould work fine. go with the orange if its a unique color of orange, theres orange engines out there but all the same orange. maybe make the cover black?

i was talking to m y metro friend (he isnt gay, he is metro!), who does paint and body work on cars and he was thinking like a HEMI orange, and a flat black engine cover. what do you think?

im kinda lazy to go to the store, can i jus wash everything with simple green and water?

it turned out perfect, although its not done you get the idea of how its gonna look. all i need is a gasket set for it and it'll be complete. oh and i forgot what the timing mark on it is! so i need to figer that out, i thought i did 1 time but the counterweight would hit the cam lobes, then i thought i did again but the end of the rod hit the camshaft. i need to get it right. oh and does anyone know the torque specs for these parts? (rod head, any bolts on it )

i never use torque specs, i tighten as hard as i can without stripping, are you going to put a bigger cam in while its all apart? you sould reseat the valves while its apart too, itll give you much more compression, that way when and if you need to rebuild it you know its the rigs or the piston.
