Kohler gas geset no fuel to carb

Question edited for clarity.

Are you using Ethanol Fuel in it. That fuel rots the inner lining of the fuel pipe and blocks the flow. Replace the line. also remove the carb and blow out all the jets. If you remove mixture screws, screw them gently in first and count the turns, and write it down. Then remove and clean. If it has a primer bulb, replace it.

There are several things that could be causing your Miller 225 with a Kohler CH18S engine not to get fuel. Here are a few things to check:

1. Fuel line - Make sure the fuel line is not clogged or damaged.
2. Fuel filter - Check the fuel filter to see if it is clogged or needs to be replaced.
3. Fuel pump - The fuel pump may not be functioning properly. You can test the fuel pump by removing the fuel line from the carburetor and turning the engine over. If you don't see a steady stream of fuel coming out of the fuel line, the fuel pump may need to be replaced.
4. Carburetor - The carburetor could be clogged or not functioning properly. You can try cleaning the carburetor or replacing it if necessary.
5. Spark plug - If the spark plug is dirty or worn out, it may not be creating a spark to ignite the fuel in the engine. You can try cleaning or replacing the spark plug to see if that helps.

Points to dirty carb... Clean Carb. But first. I know it's new, but is fuel pump pumping? Pull line off pump going to carb, crank engine to see if fuel is pumping out of the port. Is it installed correctly? Center line pulse line securely connected to valve cover or wherever it is obtaining vacuum from. Are you sure pulse line has no breaks, cracks etc.? Then pull line off pump on the tank side, is fuel freely flowing out of line on that side? If all the above test good, then you have a dirty carb, and it needs to be pulled off and cleaned. Have Fun!

1. Screen at bottom of gas tank clogged.
2. Inline gas filter clogged, not letting gas flow through (common),
3. Rubber gas line collapsed pinching off fuel,
4. Needle valve in carb stuck closed (common)

check for power at the fuel solenoid

Are you pulling the plug to check for wetness after cranking it a few times, WITHOUT using the starting fluid? Also, I would recommend using carb cleaner in place of the starting fluid. Starting fluid runs the engine VERY hot for a brief time and can possibly damage rings, valves, and aluminum parts.

It could be fuel pump or carburetor. Make sure tank valve is open (if equipped), remove fuel line from carb and carefully have someone turn engine over, if you get a good stream coming from line you know pump is good, then you know problem is in carburetor. Hope this helps.

first check for power going to the solenoid on the bottom of the carb its a anti backfire valve if you have power there when the key is cranking and when turned on the solenoid might just be stuck if that works maybe the gas that was left in the carb turn bad

Even if that was true, the car would run for 20 seconds without any fuel in the line, because the carb would have gas in the bowl. Why was the fuel pump replaced? How do you know theres no gas in the line? The check valve in the fuel pump should keep fuel from going backwards into the tank. The carb should hold gas, if not, find out why.

If the engine is running rough then this could mean that you have weak spark or valve adjustment. When an engine runs rough it will not burn all the fuel, which will create excess fuel in the air cleaner housing. Also, make sure the the float is closing in the carberator.
