ok head is back on. Now my trian of thought is to get some 1/8 inch mesh screen, sandwich between two carb base gaskets with a thin line of silicone sealer on mesh so it doesn't flow into intake opening,extend mesh slightly outside of gasket edges fold down when installed and bolt it all back on. That will keep any loose screws from traveling there agian. I don't beleive it will interfer with fuel/air mixture as far as power. What does everyone else think?
Did find one bent push rod #3 cyl  exh valve, rubbing on head guide hole, so replacing it. Valve doesn't push or move laterally in guide with a small pry bar,Lightly pressuring it.
