Subaru EH72-2

Landmaster/Hybird Just rebuilt the carb- and it runs good for about and hour stops running,and oil light came on, pulled the dip stick and full of fuel.. Im thinking the fuel pump is pumping fuel in the crank case... need help

With those vacuum pulse pumps it is possible but should see leaking through the vacuum port under a pressure test.  Also double your carburetor assy as there is an o-ring before the fuel control needle valve that can leak if damaged. Again this a pressure should point there.

A couple possibles that I can think of.
 
1> Vavle clearance too tight and the ACR is bumping a valve open slightly or
2> Intake not sealing completely at idle. Leakdown test should indicate this if this is the problem.
