John Deere 185 running issues

You should be aware that this engine has a "automatic compression release" so you have to make sure that the exhaust valve is closed after top dead center.

I made sure engine was at TDC and set the valves correctly. This did not correct my issue and the mower is still doing the same thing. It will not run unless the choke is on and it sounds like it is running weirdly

Still sounds like a carb problem. Take it off and completely dissemble it. Make sure you take notes and photos of it as you dissemble it. Thoroughly clean it using carb cleaner and then put it back to gether using new gaskets, and valve seats.

That was my initial thought on what the problem was and I did that, mind you this problem started when I pulled the head off and put it back on

At this point i will take any suggestions to what it could be because if i need to replace something i want to make sure that is the problem

You sure picked a bear of a engine to work on. The valve spec for your engine is .06 not .05. That could make a difference if not adjusted correctly.

Valve adjustment specs.

Luke ...... You said you cleaned the carb.....If you have the Nikki 2 BBL on your engine then something didn't go back together right..... Lots of parts on those carbs......

If you are still here I can shoot you a link for the service manual on the engine .....

Some more info on what’s going on. I checked the valves again, they are set right and i know the engine was at TDC. When i start it on choke it starts up but when i back off choke the engine shuts down hard, like i turned the key off with it running at high rpms, that sort of sound.
