My old faithful Electramac EM14 is still going strong. What I need help finding is the small part that allows one to tighten the chain. I think it is just a sliding notch - a tightener. My model number is 40010202 292 and the serial number is 11-246453. Its a two hp 11 amp model. What I see on the newer electramac is a body redesign, color change and a pigtail plug but mine just has the plug at the back of its bright yellow casing. Can anyone make a suggestion on how to identify the part number and then actually buy it? Thanks
