hondaspree.net is dead. I recently came across an 84 and needed some advice and parts. I have multiple posts that still have not been commented on in weeks. I was able to figure it out and have moved on. Anyway the 84 had the same issue. I removed the oil injector pump and drive. Used a hand operated vacuum pump accessing the crankcase through the oil injector opening and removed the gas. Reinstalled the oil injector and mine fired right up and have had no issues. I did also replace the petcock with a new one.
