I've got an 84 bayliner Capri with the 4 cylinder AQ125A engine and a solex 44PAI downdraft carb, I have replaced the spark plugs, plug wires, cleaned distributor cap and points and regapped the points to 20,000 not sure if that is the correct amount or not? Also I have rebuilt the carburetor but I cannot seem to keep it idling in neutral, it will idle at roughly between 1000-800 rpm momunterally and then slowly looses power and stalls out on me, I have tried adjusting the idle and mixture screws the best I can but does not seem to be helping..... any suggestions?
