I am not a mechanic by profession, but have a little knowhow on that trade.I recently buy a 1988 daihatsu charade(3 cylinder engine).Due to the presence of oil in the radiator water i was opted to replace the head gasket,regrind the engine valve,and replace head seals.When the head was done i find it hard to start the engine,so i buy a new distributor contact point,spark plugs,and high tension cables.The car was able to start but i find it hard to keep a good engine idling.Is my carburator defective.Could anyone kindly teach me how to adjust proper Air/Fuel adjustment.And one thing more, there is still bits of oil in my radiator water but not in the engine oil sump.I flushed it twice but still bits of oil appears.I urgently need an experts advice.Thank you
