K241 heats up and won't start

Recommended Posts

johnmonkey
I replaced the 10 hp k241s on my 1978 AC 710 6 speed with a k241s from an AC 310. The engine starts up and runs good. Twice now she has bogged down in wet soil or heavey grass and died. I tried to restart but she floods right away (gas drips out of the carb [float prob?]and she will not fire). Is this a float problem of could it be the the electronic module overheating??? Any help would be greatly appreciated. Thanks John H

John, Did you remove the shroud from the engine and check to see if the fins were clean? I just removed the shroud from the 12 Hp that you gave me, to find that the fins were completely clogged off on the shroud side. I got the rings in and the new head on. Got the shroud painted. Have to paint the block, make some throttle linkage and a couple of pieces of shrouding. Hope to have that one running soon.

Rod, you are another that mentioned clogged fins. I have been trying to alert people to take off that shroud, probalbly around the exhaust side and blow it out. It would most likely give those people more engine life.

John, Coil could be breaking down from heat. Also make sure that fuel line is not near any hot parts of engine. A hot fuel line can cause vapor lock. Pull line off of carburator and make sure fuel is flowing. The 61 Wards does this sometimes. Once fuel is flowing through the line and it is re-attached to carb it will run fine. BLT, The oil and dirt caked in the one I just took apart couldn't be blown out. It was like hard bubblegum. Had to scrape it out with a knife. Rings had no tension when I took them out, from overheating. Doesn't take much to kill an engine, but It also doesn't take much to prevent their death.

      folowing  this from a link at the downloads.  I just rescued an AC 920 with the lambodini diesel. I can' t download  yet .  Where did you find the PDF copy you posted. . I would like to figure out how to adjust the injection pump. 
      I assume it's a bosche, correct

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
