yup i checked it with a meter, ac output.it doesn't make sense. you can get a full wave bridge rectifier at radio shack for like 5 bucks but the biggest one i saw was 25 amps. might last for a while but id try to find a bigger one. it all can be made to work though. while your at it get a heavy...

a tuned expansion pipe on a two stroke pushes back in waves at the right time to push the fuel air mix it spit out back into the cylinder. they dont need backpressure. scavenging is the mass and speed of the exhaust gasses continuing out of the pipe creating a low pressure area(when the exhaust...

i was just working on doing the same thing yesterday. i got a 90 cubic foot cylinder with gas and regulator for $246 bucks at airgas. was going to use the HF small air blow gun to on/off the gas after the regulator, maybe foot pedal or mount it to the torch. you can drill through the bottom of...

havent touched it in a while. broke and had some real car trouble so.... i'll be back!

cool. i know the feeling of not having what you need. keep it up!

i figured the drive stuff was gonna be complicated. still pondering?

i was gonna use my manco for my duraforce project, but its bent and tweaked out of square and i'm not sure its crappy steel is up to that! winter setting in i'm building a new frame with basically just the rear axle remaining. using the front axle from my old quarter midget. strongly suggest...

and you don't want it to be your last my friend!

i dont know of any race kart that used a plastic steering wheel with a through the shaft bolt to secure it(same as my manco). hell that wheel could break off in your hand over 35-40 mph. get a race kart and transfer all your good stuff at least. now back to my Honda gvx140 powered, gm...

may be a bit late now but, putting her on a dirt bike away from said idiots on the road, to learn bike control is your best bet.

that front end and the side of the seat look like my manco. they look like a rupp but the flat brace that goes vertically is much wider on a rupp. if that is a manco(or sears or whatever) it doesn't matter how beefy the rear is, my front end is bent and the whole frame is knocked out of square...

I just did some reading and fully agree with toystory. "guru" is talking real stuff and nonsense all in the same breath. dont give him your hard earned money.

i wasnt aware of the trackmagic brand, looks emmick by the aluminum tank and frontend but i just got my first race kart(margay prox) myself so i could be wrong. good luck

i would say your geometry is way out in the front end, but you have all the parts a nice welder and ambition. do a little research on the front end and it can be rebuilt right. nice work on you your first! you on the east coast? maybe i can help.

its an emmick chassis(very well liked by anyone who has owned one) i dont know enough about them to tell you specifics, but it looks about nineties somewhere to me. google emmick chassis and you should find abunch of hits. vintage karts forum can prob help too. http://www.vintagekarts.com/forum/...

been real busy with other stuff but i got some work done a couple nights ago. wood pattern for the side plates of the trans are about done, just need to plane it down to 1/2 inch for casting. gonna order some shaft couplings that will be the center for the pulleys. i build rc air planes...

Any progress?

yup. i'm not payin through the nose for a 1" clutch. plus with the underdrive for first gear it will let the motor spin up more. its comin along, going away for the weekend though.

I'm puttin a rusty crusty 5/8" max torque on the output of my three speed, with a big carb and open pipe the duraforce has to be 8 or 9 horse power. all the same one i've seen new say up to ten HP for four cycles. any takers on how long it lasts....

i'm on trans redesign about 3.5 now. got it to wood and pulley mock up arrangement and found i didn't have enough slack for the other pulleys to spin free when not tensioned. moved a bunch of stuff around and it actually is packaged as a whole better now but makes a couple of thing more...
