head was sent away n shaved,there are no oil leaks anyehere (no oil stains on the floor,i carnt tell if its using oil yet as i dont want to run it and do more damage.

it did over heat before which is why i fixed the head, could the damage be done from then,

i think it has low compression, all 90psi but im not sure if i did it right cheching it while running without fuel pump on and only on 500rpm, i carnt get the idle revs higher

the smoke is pretty bad it dose choke u in the cabin so somehing is not right.
