Hi all - I have a 4 CYL OMC 2.5L with a Rochester 2GC 2 Barrel carb. Carb has been rebuilt and engine runs fine. Last month, the mounting bolts for the carb to the intake loosened causing hte carb to suck air. Unaware of this, I kept increasing my mixture until I realized the problem. Now that the leak is fixed, I can't seem to get the carb back in tune. Starts cold and idles fine, dies when I throttle up (even very slow). Anybody know the best settings or how to adjust the 2 barrel carb?
