350 small block

i dont know what to do here. My idle is slightly off-set but thats no really biggie. i adjusted the carberator and my idle was fine for about a day. im thinking my timing needs to be adjusted but i dont see how that would account for the oil pressure dropping to almost 0 every time i stop at a stop light or stop sign. im not sure if the carberator is causing this or if it's something internal.

Oil pressure will drop with low idle. What is it at when it's at near zero? Raise the idle to help with an old engine if need be.

What is the overall state of this engine and history? Miles on it, recent work etc. Has a timing chain ever been done?

Oil pressure should be checked with a separate gauge. Worn main bearings will drop it too low. Also possible the oil pump itself just can't do what it used to.

What are your intentions with this vehicle? Is this just a handy driver or a resto vehicle? That will matter on how you approach this,
