Rebuilt top end of engine now carb idles much higher?Please help

Rusty yes the initial timing is at 36deg at idle based on the timing light and when I tried to lower the initial timing it seemed like it was going to stall? I thought that initial timing was supposed to be around 15-30deg. I was confused by where it was set at? Did I not move the distributor far enough? I could of swore it was going to stall out if I tried to move it much lower. I made some marks on the engine block and the distributor so on reassembly when I put it back in and 1 cylinder was at TDC it seemed very close to what the initial timing was set at maybe 38deg it that possible? I know there are probably multiple things going on here.
