70HP 1974 Evinrude outboard

by Steve and Karen

When starting out slowly, it seems to misfire and when it runs for a while and we stop, it won't start until it cools or we keep cranking it with the choke up. When we are ready to give up, it starts. Each time we go out, it gets worse. It runs fairly smoothly at high speeds. We just had the 3 carburetors rebuilt. The battery is good. We don't want to keep pumping more money into it. It was run on mouse ears for a long while and refused to act up for our mechanic. Help!
