Craftsman Lawn Tractor will only run in full choke

I have a craftsman 18HP (Briggs&Stratton) DYT 4000 (Model 917273634). It sat over the winter with a little gas in it. Ran fine when I put it away. Now when I start it, it only runs when its in full choke and sputters even then. I've removed the carb and checked all the jets and passages, they're clear. I know its fuel related because I've gotten the engine to run by spraying carb cleaner into the intake throat. This way it runs wherever I put the throttle. I'm aiming know at the filter and pump. Any history of this engine losing vacuum for the pump? Is there a one way check valve from the tank to the pump? I ask because I cannot get air to blow back into the tank.

    I checked clearance on all the jets. Another thing I tried I checked is that the solenoid on the bowl was working, it was. I changed the filter and still have the same problem. It just seems like its not getting enough fuel. I'm going to run a separate hose into a gas can and see if the pump draws it up. If not, perhaps I'll change the pump.

When you had the carb off did you clean the low jet with a welding tip cleaner? This solves most lawnmower hibernation problems. Next year empty the fuel tank completely and spray a little WD40 or an eqivalent into the tank and plug hole.

Your PTO safety switch is opening intermittently. Would help if you would always add your model # such as 917.100000 that way I could look up on Sears site and tell you approx. Location of switch.

Hard to start lawn tractor


I have 2009 lawn tractor that will not start (from day 1) unless I use a small squirt
of start fluid into the air cleaner area. Nothing else seems to work. The battery will run down before it starts. Once engine is warm it starts great. Love the tractor,
hate the starting problem. Elevation is not a problem in michigan.

What is on the flywheel?
You can wash it off with water spray or clean with soapy water. Let engine cool down before cleaning it. Let it dry before running the engine.
