Opel Key Master
I just put in the combination cam and chevy valves in my 1.9 engine. Timing seems correct, but I cannot keep the engine idling without keeping the butterflies to the choke closed. I changed the gasket under the carb, doped the threads on the intake manifold, and still runs rough. Tried to richen up the mixture, but wasn't any better. Could it be caused by the booster? Any ideas?
