Well It was a cold windy day yesterday so I took the day off and tinkered in my garage. I have a box of junk parts that I acquired with a tractor package deal. More of a basket case deal as everything I bought was owned by some kid that must have suffered from A.D.D. I didn't care at the time as I was only focused on getting the ss12 hydro. So anyway I decided to grab a carburetor and see what the issues with it were.
1st issue I had to address was the main jet, & float bowl seems when he was putting the float bowl on it was leaking so he kept tightening it until it snapped off. No biggie I have ez outs and got that fixed right away.
Next thing I found was a sloppy throttle shaft. This was a bit more tricky to fix. I had to remove the shaft and fit a brass sleeve over to shaft so that it was larger. I had a sleeve that goes over the shaft but it was to snug to slide on easily so with my torch and patients I got my brass sleeves installed. So now I have a throttle shaft with slightly bigger ends but I now see that the holes the shaft goes in is slightly wallowed out. Thats ok at this point because the sleeves I added to the shaft are to large to fit anyway. I was planning on sanding the sleeves down to fit but instead I drilled the holes for the shaft slightly bigger to accept the new sleeves. Oh my fits like a glove.
I have the carb soaking in sea foam and just need a rebuild kit for new rubber. Its missing a few parts like the pin for the float and the retainer clip for the needle valve, but it all comes in a rebuild kit from what I see.
After all said and done I see that I am not the only one that has had throttle shaft issues on these so I will try and take some photos and explain the repair better for anyone that needs the info. I use a brass sleeve nut from a plumbing box I had. I think they are .25-.40 cents at the local hardware stores.
I was even thinking of putting a groove on the upper part of the shaft and put an o-ring on it to really seal that shaft good but as tight and smooth as it is now I don't think I want to mess with it.
