94 evinrude 120 skipping?

[ben_fishn]

my 120 is acting as if i have a skip. thought it may be carbs so i took to mechanic. he said i have good fire and compression and that carbs needed slight adjustment. ran fine on muffs. put it in the water saturday and same thing. acts as if you just yanked a plug wire off. bogs on takeoff and not running to full speed. what else could it be? stator or power pack maybe????????

could be several things...If the compression is good and the spark is good that pretty much leaves fuel..If you want to trouble shoot your electronics go here http://issuu.com/cdielectronics/doc...t.xml&backgroundColor=000000&showFlipBtn=true
get the needed tools and check your electronics. You should probably clean/rebuild your carbs. and check fuel flow

simply speaking it is either: compression, spark or fuel...you figure out what is wrong through a process of elimination...if compression is fine and spark is fine that kinda leaves fuel as the issue. assuming your compression/sparks test were done properly.

Is the fuel tank an outboard or part of the boat.Run the tank on a remote with fresh fuel. Sounds like the boats fuel tank has trash in it,possibly a fuel restriction.A vacum gauge in line will tell you if a resrtiction is present.If the boat runs fine under load on a test tank the problem is in the boats fuel system. Eliminate as much as possible.Loose clamps,hard cracked lines etc.
