Retired Wrencher 6,759 #1 Posted 8 hours ago (edited) I have this 1057. I have been working on it for a while now. In the beginning when I first put this together it ran smooth. The last few months It developed sputtering I started working on it yesterday. I had a rebuilt carb on it thought that was it. Put on another rebuilt carb. Same thing. I put on a new Kohler condenser.The others where aftermarket. Same thing. Today I will look at the points today. There new also by Kohler. I have this new coil on there. So hoping the new points need adjustment. Last will be the valves. Any Ideas after that? Thanks in advance. Feel free to ask questions.

My old Kohlers splutter just a tiny bit every few seconds unless under load and I've never got them adjusted properly whatever it is. 1 Share this post Link to post Share on other sites

Always suspected it has something to do with variable timing issues. Points variation, cam lash or something like that but could be dead nuts wrong too. Never bad enough to really worry about so I just run er. Share this post Link to post Share on other sites
