Starting issue for a briggs and stratton 18 HP V-twin Motor

I have replaced the solenoid, the starter, the spark plugs, and the ignition coil and it still will not start. The motor turns but that is it its like i still have no spark. It just doesnt want to turn over.

Wow, you've thrown some money at this. Briggs made a lot of different 18hp engines, from opposed twins to single cylinders and V-twins. Kinda need to know what you have to help. I also can't tell if you can't get this to turn over (crank), or if you just can't get it to start and it turns over fine.

You said it is like you have no spark. Do you?

it feels like there is no spark, i checked to see if there was spark but there wasnt, any ideas on how to fix that and my solenoid does nothing i have to bypass it to get the engine to start to turn

When you checked for spark, did you make sure the plug was touching metal on the engine?

If it still has no spark, disconnect the kill wire from the coil and check spark again.

i did it with touching metal and nothing. i tried disconnecting the kill wire same thing no spark but at one instance i had a little bit of a spark but it was short lived and that was when i had the plugs together, could a bad ground be the issue. Also the ground gets really hot for some reason

The ground gets hot where? Do you mean the ground cable at the battery, or the ground wires at the frame connection, or somewhere else?

You said it is a v-twin, but mentioned replacing "the coil". A v-twin has two... did you replace one or both? Did you replace the kill wire that runs between them? If not, I suspect that is the problem.

the ground gets hot at the battery cable where it connects to the body and it only has one coil with two cables running from it that connect to the two spark plugs and ill try replacing the kill wire

I'd clean that ground connection. If this only has one coil, it must be an opposed twin, not a v-twin. Replacing the kill wire won't help on that one. The v-twins have a kill wire with a diode in it that keeps the coils from backfeeding into each other. Your kill wire doesn't.

Clean the carburetor, possibly replace the float and inlet needle.
