Question about Craftsman 20 hp 42 in. Deck Yard Tractor

1 Answer

Hello, I have a craftsman dyt 4000 with the Briggs 18.5hp and auto transmission. I turned it off after running for about an hour and when I tried to crank it back up it flooded. I waited a while and it started up but ran poorly. I parked it about a week ago and when I went out to crank it today it turned over but blew the little hose off behind the carb and shot gas everywhere, I put the hose back on and tried again. The same thing happened so I pulled the air filter and it was soaked with gas. I looked in the carb and its full of gas. I have no Idea what to check first. Its almost like the fuel is running to the carb constantly with way to much pressure. Do you have any idea of some things to check?

    Thanks for the suggestion Chris I typed that up last night before taking things apart but I had planned to check stuff like that and report back my findings........Ok I have taken the carb off to try and ***** the situation. I have found that gas is in everything, The manifold vent hose had gas coming out of it and the cylinder behind where the carb attaches was full. I took the spark plug out and gas poured out. I also think the oil is full of gas as well. This motor is a ohv intek series. I dont think I siad that above. It has wires going to the bottom bowl of the carb so I assume its an electric float. I think I should start with a rebuild kit on the carb and draining everything, I wanted to see if anyone else had anymore suggestions of thinkgs to check. Im only guessing at this point its the carb or float. The bowl on the carb has no bolts so Im trying to figure out how to get it apart. Thanks in advance for any help.

    Come to think of it couldn't this all be cause if the spark plug stoped getting voltage and my wife kept turning it over too long before she got me?

What engines will fit craftsman dyt 4000 (18.5 blew w/ 290 hours)

Hi there
The only thing you have to do is have the size (diameter) and lenght (from cranckcase to end of shaft) of the shaft you have on your b&s and just go to your local Honda dealer , give them your shaft size and they should be able to give you all the options for a brand new motor . I really believe you can get a Honda 20hp model GXV620 or a 24hp model GXV670 that will replace your B & S motor .
Hope this help .

Craftsman DYT 4000, 24 hp 48" deck. While I was mowing, the blades stopped turning, started again, and then stopped. I shut down, all looked OK, tried to start and nothing. No click, nothing. Any ideas?

there is a fuse in engine compartment that might have blown causing the engine or blades not to start but what probably happened was something got caught in the blades check under the deck & see if there is & also try spinning blades by hand & see what happens
