I´m new with flatheads and not too much an engine guy. I´ve been playing with four cylinder cars for 20 years, but I´m by no means an expert on engines. Flathead engines are totally new for me. I have a 48 Mercury flathead with Strömberg type carburator with electric fuel pump and pressure regulator. I have not checked what is the current fuel pressure. Engine has Mallory two point distributor and cables and spark plugs are quite new. I checked plugs and they were dry, maybe a bit more snotty than normally. Engine is running rough and uneven, I found it impossible to drive it on idle or low rpm. I plan to disassemble the carburator next, I already checked the points, changed coil and condenser(to another used ones). I plan to buy new condenser, I suppose flathead uses an universal kind of condenser? Can you help me? I suppose there is some "do this and that" tips for flathead?
