Coleman /Briggs engine not starting low compression 60psi

[twinfords]

i have a customers Coleman generator with Briggs 6hp engine OHV 120342-0137-E2, has only 60 psi, it is back firing through carb with flames sometime, i had it started for like 2 minutes, i have checked flywheel key, cleaned gapped plug, rebuilt carb, check coil and gapped. checked OHV they seem ok, what next??

Low compression can be the result of incorrect valve stem clearances (valve lash).
One or both of the valves may not be closing completely.
