Bringing a 1970 Evinrude 18 back to life.

Hey guys I am trying to bring my motor back to life. Can't get it to start after it left me stranded on the res a couple weeks ago.
Started out by cleaning the tank, fresh mix and fresh plugs. Pulled on the starter for about as long as I could take. Heard some popping at the end and after 30 minutes of yanking smelled a little two stroke in the air.
Not sure what to do but I know I want to try to do it myself but have really no experience.
Thanks,
Carl

Spray some fuel oil mix into the carb if the motor pops you have a fuel issue carb, fuel pump, ect.

OK thanks. New problem, I was out there yanking on the starter rope and it just went slack on me, I turned the flywheel to coil it back up and it doesn't seem to be under tension anymore. Think I made things worse.
Here's to being humbled repeatedly.

I guess a better way of saying it is that the starter rope wont engage the flywheel. You can easily pull it and it retracts but there's no tension.

Just wanted to update, got everything back together and got this bad boy running yesterday. Compression and spark looked good so I cleaned the carb and finally got it running. One note is I had a bad habit of getting the spark plug wires crossed. But anyway it runs, and it started this morning after two pulls. Best it's ever run since I got it and I learned a few things getting it there.
