John Deere 322 won't idle

[cobra6600]

I have a John Deere 322, that I have replaced the spark plugs, vac. hose, fuel filter and checked the fuel pump pressure and I'am pumping more then 7oz of fuel in 30 second (could that be much?). It will run at full speed (not smooth), but will not idle. Need help in Michigan. Thanks!!!!

Welcome aboard.

I suspect you have some carb issues, either a dirty carb or it needs tuned or both. Not familiar with your JD, so I will let others assist.

If you don't get the answers you want, repost your question in the JD forum on TBN.

Again, Welcome!

Are you comfortable with carb adjustments?
With carb rebuild?

What is the history, leading up to this inconvenience?

You probably have a clogged idle passage in the carb. They have tiny fuel jets, and are the first thing to clog when dirt enters the carb.

Getting it clean usually requires carb removal, disassembly, and a thorough cleaning. Some good carburetor cleaner, and compressed air is almost surely a necessity to get it clean. Rubber tipped blow guns are very handy for checking to see if a fuel passage is cleared.

Another possibility is a vacuum leak. The line to the fuel pump from the intake manifold could be the problem. (Only if your engine has a vac operated fuel pump.)
