for the life of me i can't find the post about adjusting the 410 carb, something like 2.5 turns? ah i dunno.
just wanna make sure everything is running right, service and tune the carb and that!

any help would be greatly appreciated

I'll be honest, in my opinion carb tuning's a bastard. You'll get it running beautifully in the morning and it'll be dead on its wheels by the afternoon.

First of all, make sure your float valve is working and set properly. If you've got a Haynes it shows you how to do it in there. In my SJ I found that I had to set the float so that it closed the valve a bit earlier, so having previously set it using the Haynes method, I then just opened up the gap between the float and the needle actuator a little bit more with my thumb.

The method my step-dad taught me was to turn the idle down until the engine's just starting to struggle, then turn it back up a tiny bit, blip the throttle and let it settle.

Then turn the mixture screw one turn either way.
If the engine speed goes up, do the idle screw step again.
If the engine speed goes down, turn the mixture screw back a turn, then try a turn in the other direction.

You want to get it so that when you go a full turn in either direction the engine speed goes down
