1986 evinrude won't go over 2400rpms

[dcolpitts]

rebuilt carbs, new vro, new power pack, resistance in stator and charge coil ok, 12.82 volts to batteries. can I check voltage to power pack with a digital volt meter and should it read 175volts running or just cranking. doess this motor have reed valves?? or the slow circuit. If I dissconnect the main cable from the engine to the console and start it will it eliminate the warning system. anything here will help. I assume that the jets are fine in the carbs due to the fact it ran great for 2 yrs. commpression is all 105-118

First, the make and hp of the motor would help, and if it's a 2 stroke, then it has reed valves.<br /><br />I think it's fuel starvation. Try doing a search on limited rpm's there's a few good threads.<br /><br />Normaly checking fuel passage ways and the fuel pump for full opperation is a start.<br />Possibly try pumping the primer bulb while under way, and see if a gain in rpm's is evident. If so, then definately fuel starvation.

yes it has them for each carb.<br />mine did that, turned out to be power pack.<br />im hoping to get mine back to gether soon. <br />am trying to talk the wench into letting me park<br />it in the yard so i can finish it. <br />as is i have to drive 60 miles round trip to work on it.<br />and thats just due to the nazi homeowners association. but since mine has moved <1yr now><br />boats are parked everywhere.<br />but i know with the prez living down the street it wont be ok for me.
