Hey guys i've been working on my late 70's mercury could not find any serial #'s to give exact year but it is a 4cyl 2 stroke with with a coil for each cyl. also has 2 bulb carberators. I have cleaned carbs and replaced gaskets. new spark plugs and had to replace 1 coil that wasn,t getting good spark.
Now the problem, Motor runs great in nuetrual. when i put it in gear i can only get about have the rpms. The motor sounds like it's going to take off but then just levels out at about half the Rpms. linkage is good and throttle fully ingaged. all four cyl are sparking good. any thoughts on the subject.
