Won't run. Seems not to be getting gas. If I put fuel into carb while cranking it will fire but won't keep running once the fuel in carb is burnt of. Is this a fuel pump problem & if so what does it look like? All I see is a round black device. This engine is on a Miller Bobcat 225.

The battery voltage on a Suzuki I had would drop low enough during cranking with the electric starter motor not allowing the spark to be strong enough to run, the voltage regulator also didn't function correctly once and as the battery voltage dropped during operation engine would start to bog down and cut out due to low voltage for the ignition system.
The main jet of your carb is clogged and you need to open carb and clear the obstruction - spray carb cleaner on the bolt that holds the gas container to bottom of carb - also spray all the innards along with any tube that protrudes into the gas can.
Then using air compressor blow the sucker out and reassemble. That should do it.
Replace the fuel filter in the tank, check the fuel hose up to the carb for signs of leaking, if so replace the line, between the cylinder and the carb back plate is a rubber induction tube, make sure this has no split.
The exhaust valve opening at the beginning of the compression stroke is designed to make the engine easy to crank.
Since you know the exh. valve is opening, it means you have torn into the engine (maybe ?) because you don't really see it any other way. Did you put it back together correctly ?
IF an engine has spark, proper timing, compression and fuel it will run.
Since yours runs for a bit, I say you have a carb/fuel delivery problem.
sounds like it might be flooded. Try and remove the fuel pump fuse from the fuse block that is just in front of your left knee. While it is out crank the car and see if it wants to start and hold down the gas pedal all the way and then relase it and back and forth and once you get it to run have the fuse ready in your hand and in front of the spot to install it. and then keep the rpm's up with the gas pedal until the smoke clears out behind the car.
the other possibilities you have is a bad crank seal, or a flywheel came loose and its out of time, will it fire on carb cleaner sprayed in the carb, If it runs for seconds and , then I would say it's not getting fuel, If it only farts once or twice then I would check crank seals cause if they are leaking then your crankcase cannot draw vacumn which in turn causes fuel pump in carb to draw fuel, If you have to check flywheel pull it apart and take flywheel nut off and pull flywheel off and inspect the key that is built into flywheel to see if it is sheared off or messed up, also while checking muffler check for the opening that the mud dobbers havent put mud in muffler pipe, good luck
