    Fumble the last 5 pics show the 5021 pc which is not self propelled. I pucked it up for 30 bucks locally and it had some no name brand Carb swapped on it. The first pics are of the other self propelled 5021 which is the original mikuni. That Carb does not have a hose coming off the top either. Can you post a pic of your carburetor? Also did you run a thin wire through the pilot jet as well as the main jet? The pilot is what controls the fuel through the low speed circuit( startup and idle) the main jet isn't usually activated until about 1/8 throttle and up. With a clogged pilot it may not start or idle.

    Minors also made a cw1336 which was a 36" commercial walk behind. A true beauty and bullet proof machine

    no but some of the members here do have service manuals and are willing to scan and share pages. The manual is too big for them to be bothered by scanning the whole thing at once so some of the pages and the index have been previously been this thread. I would suggest anyone interested to down load these pages.

    I purchased a paper back manual on eBay last night. I could not find a PDF.

    I see. Neither of my current mowers have this line. It is probably a bowl overflow. It does not appear to be a vacuum line. I think that line is meant to dangle down only. Without a shop manual I can only guess

    finally got 2 pix to post. The tube I am talking about does not appear to attach to anything that I can find unless something is broken off. The tube that comes down from the air filter provides a suction and it would seem that the tube from the top back of the carb would also be used to draw fuel into a dry carb at start. The usage of the tube has me puzzled.
