Your post is very confusing.

You could have mixed the oil in too thick. Did you gap the plug when you put her in? Most come pre-gapped, but not all.

You can try spraying starting fluid through the intake. Actually, maybe I say this too quickly, I've never used a 4-mix and wouldn't know if this is OK. I would give it a try though.
