John Deere 322 Dies after 5 minutes running and wont re-start till cold again.
This year my 322 approx 1000 hours has been nothing but trouble and is still not running. At first the creep adjustment had gotten out of whack and this lead to frying the regulator and replacing what was likely the original water pump belt. My buddy who did this drove it approx a 1/2 mile back to my home and the 322 ran great for a few days after that.
Then, it developed a high speed miss and I tested and replaced:
Spark plugs, all
Coil pack,1pc
The next problem developed:
The hi-speed miss progressed form periodically to fully shutting down the machine once it started and ran for 5 minutes or so and then dies. Iassume until full operating temperature is reached? Then, the machine begins to sputter under load (mower deck engaged and quickly dies (5-10 seconds). If I shut off the mower deck the machine will run for another minute and then shut down quickly (sputter and die) as if there is no fuel.
Since then I have:
Disassembled and confirmed and readjusted the carb, no difference.
On the carb a small plug over the fuel/mixture screw had gone missing. I turned a new one and press fit it in.
Decided to try putting new new fuel in (what the heck?). In transferring the fuel out the time it took was too long, about an hour, the pump was operating at 40% of the 7oz volume spec and at ow pressure. I replaced the pump with a 2.0-3.5lb pump thinking, "now I got it!". No change, same problem as ever, runs for 5 minutes and dies a sudden death.
Then I disconnected the fuel-shut-off solenoid and it would not start, this may be a red herring. Upon reconnecting engine starts but dies same as before. Could the shut off solenoid be intermitting?
WHAT IS WRONG, I JUST WANT TO MOW MY LAWN - HELP.
