I had some luck using ATF on a smoking car by trickling it through the carb. keeping the throttle opened to keep it running. You want to see smoke, that will do it. Get the engine hot first then use the ATF or MMO, after it runs for a little while pouring the fluid, pour enough fluid in to chock it down. Let it sit overnight then it may run ok after all the fluid is burnt out of the muffler and tailpipe. If you have close neighbors, do it when they are not at home, it will smoke them out. Al
