Okay guys need some help/ advice. I just finished installing a 23 HP briggs and stratton in my argo bigfoot. All hooked up no problem. So I go to start it and it spins but no ignition. Igot fuel drawn into the fuel filter but just not getting any fire up. I poured some gas into the carb and got ignition for a few seconds till the fuel in carb burnt up then back to same situation. This is a brand new motor, wondering if it's the mixture. Anyone know how to adjust the mixture on these 23s. I found the mixture screw on the old 18 but not on the 23. Any advice would be great.
YEP ! I forgot that the newer engines have the electric fuel shut off celenoid on the bottom of the carb. You need to get 12V to it so it opens and lets the mani jet get fuel. It also can run off the oil pump pressure switch as to shut the engine down in loss of oil pressure.
Okay, As I look at the carb there is the electric fuel shut off solenoid at the bottom of the carb. There is a wire that comes off of it runs under the shroud and comes out near the starter. I was wondering what that was. On the 18 I pulled There is a black thin wire that was just fastened to a screw and I connected that in the same manner on the 23. What do I do with the wire off the fuel shut off solenoid? I need to attach 12v line to it and from where direct to the battery? Yes there is what looks like a oil pump swithc and it has a connector already on it but no wire to it. Are you guys saying I can connect the fuel shut off solenoid under the carb directly to this connector on the oil pump switch? Will this supply my 12v or do I still need to connect to a 12 volt source? I am getting fuel to the carb past the fuel pump.
Thanks getting closer

Sounds like it was setup with a low oil pressure fuel shut off. you can wire it 12v from the key or just unscrew the solenoid and remove the needle and then theres no need to wire it in at all.
Hey Junkman, glad you chimed in. So you are telling me to run a wire from the key switch to that black wire that leads to the bottom of the carb correct? should I wire to the oil pressure sensor also or can I leave it alone? The engine swap went smooth except for this aspect. Am I correct in assuming this wiring of the solenoid below the carb is a single wire set up, from switch to solenoid and no return or is there?
What happens if I don't wire the low oil pressure fuel shut off and I don't remove the needle in the solenoid?
