24:1 on the gas mix. Eskas usually just tilt back down without a release button. If it does have some kind of release, it should be easy to spot. One of my motors was really gunked up with old grease, and it was a pain to tilt. I had to strip out all of the old grease and re-lube and then it was fine. That might be the issue, but do make sure you check for a release button on the transom clamp, just in case.
