Arms doing better. Took the cast off, but muscles are sore from not being able to flex for so long.
My brother came over and we pulled out the gokart, he took off and then the chain started making a weird noise. Took a look at the jackshaft, and the sprocket is really worn. The 10 tooth sprocket is messed up, but welded to the shaft, along with the 26 tooth sprocket. So I need to find a 3/4 shaft with a 26 tooth sprocket, and 10 tooth sprocket on it.
I couldn't really find anything like it, found the part number from murray, 1201276, but it appears to be discontinued. I found replacement shaft kits, but they only contain a 10, and 14 teeth sprockets, and not the 26 tooth I need.....
Another option I have is to cut and grind off the existing 10 tooth, and replace, and weld a new 10 tooth sprocket...
Any ideas, or opinions? I'll post a picture to show what I am working with...
