So like a dumbass I was jump starting this new to me lawnmower I purchased for $250 with a dead battery, well in my rush I crossed wires and killed something. I've replaced the ignition switch, and the started solenoid with no luck. Funny thing is I found a button inside the engine bay that if I hold it down I can turn over the engine but even when doing this the engine will not stay running it will just briefly fire up.
Here's some engine specs
Model: 42a707
Type: 1237 01
Code: 95012558
Here are photos of the switch I found that if I hold I can turn the key and it will start the engine but won't stay running, I also want to add before I didn't have to hold the switch to start it, it started just fine before crossing cables.
I also want to add I replaced the starter solenoid with a 4 pole solenoid, here is a picture of how I have it wired in case it is incorrect.

First and very IMPORTANT !! provide the machine info. WE need to know EXACTLY what YOU want help with..see example ..
yes the eng. is briggs ... mower is a White..?? but we need the rest , from what I see in your pics ..
1. the "button you refer to is a safety switch , it's either from the blade engage lever or most likely the brake linkage
2. NOT entirely sure without the mower wiring diagram but your "White" mower was most likely MFG. by MTD products.
meaning it should use a 3 wire solenoid, some 4 wire solenoids use one of the small wire terminals as a ground ( like what I see in your pic. ) HOWEVER , some .. use that as a power terminal which is fed from the hot feed side of the solenoid when the key is in the start or the run position THAT could be your problem ... you need to know what type of solenoid your engine requires , found in the wiring diagram of the owners or shop service manual and WE don't know which manual that would be because YOU have'nt provided the mowers information !! WE can't help YOU until YOU help US .. Is THAT clear ..?? also lets handle 1 problem at a time jumping around creates chaos !
