I'm not exactly sure which "rod" you're talking about - I am assuming you are talking about the one from the carb linkage that connects to the transmission - which I have adjusted... Don't know if it is right though...

Also, I recently pulled the modulator to check it and it looked fine, but I can not figure out ow to adjust the thing. Shop manual says to use a 4mm hex, which I tried, but I couldn't get it to turn???
