88 70 HP Evinrude problems

[howardchaz]

Hey everyone- I have a 1988 70 HP Evinrude 3 cyc 2 stroke outboard. I've done a search and have the shop manual but am still confused.<br />Do I have a fuel filter on the engine? If so where is it? Also I changed the spark plugs with correctly gapped new ones- used a can of the decarb spray, and changed the lower unit lube.<br />I run it with muffs and it runs well for a while,<br />then stalls out , fires right back up no problem.<br />Then does the same thing. Is one can of decarb spray enough? Would it hurt to dose it with another can. Would it run better in the water?<br />Also I disconnected the vro and plugged the hole.<br />What wires must I disconnect with it? First motor- thanks for any help

Try pumping the primer bulb when it starts to die. If it picks up then you have a fuel delivery problem. I would start by checking for air leaks in your fuel lines.
