I HAVE A 41 FARMALL H AND GOT REBUILT CARB FOR IT AND WORKS OK, BUT IAM GETTING GAS IN THE OIL AND THEN LOW OIL PRESURE, I HAVE BEEN OVER ALL THE OBVESE THINGS AND THINK MAYBE CARB NEEDS ADJUSTING. ANY IDEAS OUT THERE? IF SO ANYBODY KNOW THE ADJUSTMENT.THANK YOU FOR HELPING.
 
With engine warmed up (cover grill with garbage bag,etc. to restrict air flow) run the engine at wide open throttle (WOT). Adjust the main mixture screw on bottom of carb out (rich) and in (lean) then find the happy medium where the engine runs at it's fastest RPM. Continue turning the high speed screw out 1/2 turn for a bit more richness for power. (If plowing, etc. may need a bit more fuel).
Idle the engine down and adjust the idle AIR screw (in is rich-out is lean) for best idle speed and give a bit more richness so the engine doesn't cough upon accelleration. Remember, there is no accellerator pump so "snapping" the throttle open may cause it to stumble. This is not a truck at a stop sign trying to take off quickly.
Reset idle RPM's.
Now repeat the process to assure that all is well.
 
Do not run it with gas in the oil or you will be looking at an engine rebuild soon. Do you shut off the gas when its parked?? If you don't you need to. Float may not be set as it should be and will cause that but even if the float is set right it is common for gas to get in the oil if you don't shut it off when parked
