Dang, I picked up a engine miss :(

I pulled the valve cover off and everything looked good. I did a compression test and the readings were all over the place. #4 cylinder was the weak one and it had 135# and 150# with a few squirts of oil. #6 was a low too but all the rest were in the 140#-155# range. The engine only has a few hundred miles on it and I would guess that the rings aren't seated yet which could make for uneven compression. I wouldn't think the 130# compression would be low enough to cause a complete dead cylinder. I think I need to put it back together, adjust the valves and take the carb top off for a look inside and may-be blow out the idle screw passages and make sure the acc. pump squirters are even.
