JD Gator only runs with choke
Fuel pump. If it looks like the one below - or this one ( http://www.mfgsupply.com/img/rotary/22-10875.jpg ) - replace it.

someone mentioned a fuel pump but it appears to be pumping fuel,

"Appears" is the operative word. If in fact your engine is a Kawasaki - and if it's got the vacuum type fuel pump - you probably need a new one. They only last ~18 months on my 15hp Kawasaki V-twin (just installed 4th fuel pump on a 5 year old engine). The diaphragm weakens (or leaks), and can't pull enough fuel from the tank. Air/fuel mixture gets too lean.
Half choke
1. tries to correct the air/fuel ratio
2. pulls more vacuum, therefore more fuel.
Only in this case, all the extra fuel does is simply make up for what's NOT pulled by the failing pump diaphragm.
Failure to replace this type fuel pump promptly will eventually result in a complete diaphragm rupture - and result in gasoline in the crankcase. Be watchful of a rising oil level. Been there, done that.

are the fuel pumps rebuildable?
|

Not if you've got that vacuum type I identified, they're sealed. Virtually no moving parts anyway. Last one I priced at the local small engine shop was $34 plus tax. If you want to shop around, click below for an example.
Like I said, my 2004 Kawasaki engine has been going thru them on an average of 1 every 18 months.

fuel pump (part #AM109212) is actually kawasaki part number 49040-2066. The best part of this is that I found parts to actually rebuild these pumps

Helps me, thanks. Didn't realize the metal variant was actually rebuildable. The OE pump on my Kawasaki engine was plastic, and I've been wasting my money on replacement plastic versions ever since. The fact that the case is heat-welded pretty much discourages thoughts of rebuilding. But I'll now buy one of those metal ones to have as a shelf spare for when this current plastic one inevitably fails.

Good catch. Hang on to that extra fuel pump though. I guarantee that you'll eventually be glad you kept it.
