I'm really stumped with this. Rebuilt this 1980 12a engine and I can't get it running. Started up one time last summer but I shut it off thinking it'd start again but nope. It doesn't even sound like it's trying to fire at all. Just cranks. It's got fuel/spark and as far as I can tell decent compression for a rebuild. I don't have a rotary gauge but with all plugs out it blows good air out of the holes. Only thing I can find on it is to pull/push start it but I'm trying to avoid this unless really necessary. Anything else I can try before pull/pushing it?

Thanks for any assistance!
