On a Suzuki King Quad 300, the timing marks are typically located on the crankshaft and the camshaft. To find them, you may need to remove the timing cover. The marks are usually indicated by a notch or a line on the flywheel and a corresponding mark on the case or the camshaft gear. Ensure the engine is at Top Dead Center (TDC) for proper alignment when checking or setting the timing.
The pulleys have marks that line up with marks on the case, See link below for complete step by step how to with pictures.

There are no timing marks on the water pump.the only timing marks are on the crankshaft and camshaft gears.And if you're working on a quad-four engine as I suspect you are,you will need to line up the holes in the cam sprockets with the holes in the block and insert pins to hold them in place.The correct size drill bits will work good for this if you don't have the special GM tool.
Crankshaft gear timing mark up, camshaft timing holes over the small holes behind the pully, they should be at 6 o'clock. facing straight down. if your over 100k make sure to buy a new chain and tensioner.

To replace the timing chain on a Pontiac Grand Am SE with a 2.3L quad OHC engine, first disconnect the battery and remove the engine covers. Then, drain the coolant and remove components obstructing access to the timing chain, such as the water pump and front engine mount. Align the timing marks on the crankshaft and camshaft, remove the old chain and tensioner, and install the new timing chain, ensuring proper alignment. Finally, reassemble all removed parts, refill coolant, and reconnect the battery.
I might be wrong but on a Suzuki king quad the tire pressure should be 36 psi!
The timing is ground in the crankshaft and not adjustable.
