1981 Evinrude 115hp won't start... again

[TBarCYa]

You guys were a great help several months ago when I was originally trying to get this engine running after about 5 years sitting idle. Since I got it running back then (April I think) it hasn't been started and when I tried starting it today, it won't start. <br /><br />I have fuel coming out of the carbs when using the choke on the key or the manual choke so I know the carbs are working and I verified that I have compression and spark on all 4 cylinders. When trying to start the engine, I get a bit of smoke (bluish white like it's burning oil) from the two holes in the housing below the power head and I get oil coming from where the prop meets the bottom of the housing. If this was a 4-stroke, I would say that having air, fuel, compression, and spark would be good enough for it to run but I'm not as 2-stroke savvy so if there is anything I should look at, please let me know as I was hoping to get this boat wet tomorrow.<br /><br />Thanks in advance for your help.

Go to the Engine Won't Start in the FAQ.

Thank you. I've been thru all of that and the engine still won't start. I had thought maybe the oil coming from the prop would be a clue but I don't know what it means.

Is there any way to check the timing without the engine running?? The Clymer manual only states to check it while running but I want to make sure that the timing is correct and not causing my problem. I have a timing light and know how to use it, I just can't find what the timing should be when starting.<br /><br />As an update, it pops and smokes but refuses to actually start. I've got the throttle in the start position and it cranks forever, but just refuses to start.<br /><br />Thanks.

Nevermind the timing. I think I found the problem. It appears that my number 2 cylinder only has 30psi compression whereas 3 and 4 have 90psi and 1 has 110psi. The number 2 cylinder is scored and the number 4 cylinder looks like it's been overheated. One and 3 both look excellent.
