DaleC Posted October 25, 2003 Posted October 25, 2003 In working on the Big Ten, I found that the throttle shaft hole is flat worn out. Is really allows the butterfly shaft to wobble.Question. Has anyone ever tried to repair this. I imagined in my day dreams that it could be drilled and bushed with bronze. If anyone has ever done this, where did you get your bushing. I guess that It could be made easy enough, but being able to find a bushing that would work would make it a whole lot easier job. If I do do this, am I going to find that the wear is also in the shaft diameter as well as the hole?
gregc Posted October 25, 2003 Posted October 25, 2003 The throttle shaft bushings are available from a Briggs dealer.
DaleC Posted October 25, 2003 Author Posted October 25, 2003 Amazing, I had never even thought to ask the local Briggs dealer about that. Thanks Greg:D
EDS Posted October 25, 2003 Posted October 25, 2003 I put a bronze bushing in a Kohler carb once. I got the bushing at a local hardware store. Held it in place with JB weld.
ka9bxg Posted October 25, 2003 Posted October 25, 2003 If you do bush the carb you must replace the throttle shaft. They are not that bad in price. I am lucky in I have a bridgeport mill at work that works great for that kind of job. I did a carb on a simplicity that had the bushings in it already.Bob
DaleC Posted October 26, 2003 Author Posted October 26, 2003 I figure rebushing will have to help smooth operation out. The motor runs smooth now but the shaft is all loose and bouncey. I hate loose and bouncey. I am going to tighten up the linkage by putting springs that run between the linkage hookups. I have worked on several older briggs 3 to 4 hp vertical shafts on lawn mowers that are set up that way from the factory. I am sure that it will help keep every thing tight and give better response to the governor, etc.
