Missing part

[Sarah512]

Hi everybody! I was wondering if anyone could help me identify the missing part underneath my go kart. I've included a picture. Any advice is greatly appreciated! It has a tecumseh 3.5 engine on a carter frame. It runs but doesn't drive because of the missing piece.

 

[redflash]

is that a verticle shaft engine ? Can't figure out what that wheel or pully is.

It is. And the plate with the bolt spins, I'm assuming to move the wheel/pulley system but I can't figure it out

I cannot figure out how the gas tank can be laying on its side. Looks more like a lawnmower frame than a go kart and Carter Brothers made both lawnmower as well as go karts. couple more pictures of the complete kart would help.

I took the picture at a pretty weird angle but I can post more, I really appreciate your time! I had the tank off to replace some fuel line and the filter so it's not where it normally goes. I hope these pics help.

Ok, stared at it a little longer and the rust grove on the vertical wheel is for a friction wheel mounted on the center shaft that spins with the rotation of the engine moving the center jackshaft. This is how a lot of rider mowers worked back in the 70's. When it got wet it worked as well as those boys in Washington.

Thank you so much! With the friction wheel, does that then connect to one of the arms below? (If that makes sense)

In order to get that going once again you have to clean up the friction wheel attached to the engine crankshaft. It cannot have any rust on it or you will wear the friction wheel you add to the middle shaft where the threads are exposed. Where do you find such a wheel?? It will be steel in the center with a very hard rubber bonded to the OD of the part. I asked a couple of people very familiar to that kind of drive system for their help. Measure from the middle of the threaded shaft to the wheel on the crankshaft of the engine so we can find out the diameter of the wheel needed.

I cannot thank you enough for that explanation! I'm going to measure it as soon as I get home. Thank you so much again!

I see the Kasea brand and serial (?) number, what is the model number?

Just put on my glasses and see the cable that lifts the friction wheel up to make contact to wheel on the engine so there is no clutch needed. Make sure you you get this arm well oil and loose so it lifts easy when you pull on the cable. This is how you make it move forward is with the cable that lifts the friction wheel against the plate on the engine.

I personally would scrap that motor.....get a harbor freight 212 horizontal shaft motor and begin with a simple, standard clutch and chain drive system. much simpler and easier to mod for future power

Redflash the problem he would run into is he would have to completely re-design the kart. There is no way he can get down to the axle by going to a horizontal shaft if you look at the pictures a little closer. I do agree with you this wasn't a big seller for Carter Brothers but it worked and they saved on not using a clutch or torque converter but it was very complicated. Some engineer must have had a fun time with the design-- job security. I don't know how mechanical Robert is but to toss everything and go to a horizontal set up he would put a lot of money into the project where if he can get the friction wheel he is done. There has to be some other people out there with the same kart who could look at the wheel on their kart and get a number off off it. Carter Brothers bought the wheel from some one like Snapper, MTD, or Murray. I am "old" and I still fix things. and this is fixable the way it is. He just has to get lucky with a part number.

Jim, I see the Kasea brand sticker and serial (?) number, what is the model number? I don't think Carter built this. Must be China.

 

[redflash]

I;d still rework the whole system....then I would know exactly what I had. But thats how I do things

I tend to agree most likely it isn't Carter Brothers. Couldn't find anything like it in the Carter Brothers brochures I have. Did look at the Kasea brand go karts and the front end does look like some of their models. The Tecumseh engine does throw you for a loop. Someone must have parts around for the Kasea since so many outlets carried the karts. Back yard fun kart production stopped in the United States in 2005 thanks to lawyers. The lawyers then all moved to Washington where the big money is.
