240Z not running right

Thanks for the vacuum advance suggestion...I would have forgot that.

I'm trying to fix the L24 without pulling the engine apart...as I think since it was running correctly since I put it all back together for 200 miles or so...whatever problem I have now I don't think should require pulling the head.....I'm thinking it must be simpler than that. I could be wrong of course....but I appreciate the suggestions! I get a break from school in 6 weeks and plan to spend some time with it then. I'll check the valve adjustment for sure, and will probably readjust the float levels in the carbs to start with.
