Evinrude XP 150 1990 2 Stroke Not Running!! HELP!!

[nano_b123]

Hey Everyone,
I have an Evinrude 150 that I have been fixing up slowly for a while now. I have been working on it and i had it running a couple of days ago. Everything ran great until yesterday. I tried to start it and it started very strong but ran for about half a second to 1.5 seconds max. It also seems like the fly wheel gets stuck every once in a while when starting. The carbs were cleaned, the premix has extra oil, I give it starter fluid, and all the spark plug are firing. Don't know where to go next! Hopefully its not something bad. It has been getting pretty cold outside here in NC so hope that doesn't have anything to do with it. I ordered a kit and will do some compression tests soon. It seems like it has good compression though. Is it a fuel delivery problem? Any response is appreciated! Thanks guys.

Did some more testing today and I am leaning more towards an electrical kill problem but still not sure what’s going on.

Drained and inspected the gear oil ?-----Any water in the gearcase ?

Figured it out! Gearcase is fine. Replying because I know how much I have used these forums so wanna help anyone else out. My oil sensor was bad in my auxiliary tank so I cut the wire on it to stop the beeping. Turns out it was killing the engine even though it was disconnected from the sensor. I had to disconnect the sensor wire which was an orange right after the big red plug and I had to unplug the big red plug and plug it back in to reset the switch. Everything is working perfectly now.

I am not sure of any switches that need to or can be reset on a 1990 motor like yours.

Oil sensor only causes beeper to sound or not, wont effect any ignition circuits. And as Racer stated no switches to be reset. You have a problem that is likely to go major.
