I have a 1984 4winns IL4 120HP merc. There is no vacuum advance line going to the distributor, nor do I see a fitting that a line could attach to. Ditto for the 2 barrel merc carb. What gives? Is this normal?<br /><br /> I am trying to figure out why the engine dies when I give it gas-I have to baby it through a dead spot that starts just as I start to accelerate. (shifts fine, so switch is ok. And I see a spray from accellerator pump in carb also)
