Looking for ideas of what to check next.

My engine was running but had started burning to much oilit's been about 150k miles since last rebuild.

I dissassembled the engine and cleaned the rings that were covered in carbon. Honed the block and reassembled using the same rings. Compression was good at 160 across all 4 cylinders before i took it apart. I studied the burning oil was from clogged oil control rings which once apart were caked in carbon and could barely move. Now that it's back together it is very difficult to start takes 10 or so cranks. Will not stay running. My compression is now 115 to 120 on all 4. Im not sure if this is low because the rings haven't reseated or that reusing them was a mager mistake

Should the engine be able to start at 120 compression?

Ive checked timing twice cams and cas are good. Engine has spark and fuel. Plugs after it only running for 15 mins are very fouled and are completely black. Is there anything else i could be missing before i tear it back down and put new rings in?

Some specs
S13 sr black top
Haltech 1000 running on map
850cc injectors
Cp pistons and rings
