After reading for a month or two this is my first post here. This problem has got me really dumbfounded .... and I'm usually pretty good at sorting these things out. Bought used JD 757, 2006 model about a month ago. Motor is the Kawasaki 25 HP FH721D motor. Rebuilt motor, new pump, new clutch, new other stuff. This mower had been sitting a while with 900 hrs on it. It appeared to have been abused before getting rebuilt. Ran it for an hour cutting the grass and parked it. It ran great but I noticed the altenator light was on when the clutch was engaged at operating speed. It was off if the clutch was not engaged. Concluded the voltage regulator or stator was not pumping enough current. Went to measure the AC current output of hte stator and notice the plastic electrical conection to the VR was slightly melted. Didn't know if that was before or after the rebuild. Measured the voltage output from the stator and it was 32 volts AC. Specs I had said 26 volts, but JD Mechanic said 32 was about normal. Well the wiring harnes was fried so I replaced Stator and VR. Also replaced the coils while I was at it (they looked bad). Pulled the engine, to make the repairs and reinstalled the engine. Go to crank it up and it cranks fine at idle. Back it out of the garage and rev it up and it goes dead quick. Try to restart and it just won't start. Checked spark fire while cranking, and they fire. Checked fuel pump output while craking and it pushes fuel. I saw the choke linkage was off and concluded the choke valve wasn't choking. Fixed the choke linkage and it still won't crank when idle or when at full throttle. Pull breather and poured some gas in carburator. It cranked and reved up nicely until the gas ran out. Checked the fuel solenoid and it is clicking. I'm getting 12.6 volts to it. I will pull it tonight to see make sure the clicking is indeed moving the solenoid. I'm confident it is. IT RAN GREAT two week ago. When I try and start it, there is no change to the pitch of the engine when I choke it. Its pretty obvious its not getting fuel. However, it ran great before I put the stator on it. Can a carburator get clogged in a week just by tilting from side to side while removing the engine? What else could it be? Another thing that may be ok but I thought it strange. When the throttle moves from idle to full, nothing on the carburator moves. It move the control assembly on top of the govenor assembly, but does not open (or does it close when accelerated) the throttle valve at the carb. Is this normal? I'm speculating the throttle valve opens by the force of the air flow accross it. I didn't touch the carburator when I rebuilt the electrical system. I did have to drill out a broken bolt that mounts the fuel pump. I had to disconnect the fuel pump. Its possible I got some small shavings in the fuel pump, but unlikely. HELP!!
