Still overheating

I'd use where you are now as a base. Count how many turns to get to " won't go no more" and bring it back out the same. Then 1/2 turn it in/out each 'til you find the sweet spot (max idle) and then drop it down the smidgen. Hows that for technical talk? That's just for the idle mixture. When driving your not using the idle circuit. But, if you think you're running lean, check the plugs. They tell everything. ( as long as you know what you're looking at ) I think every D.I.Y manual ever made has those pictures of plugs operating under rich/lean/just right conditions. Speaking of which, make sure you have the right plugs in there too and , of course, they're gapped correctly. Make sure you don't have a vacuum leak as well 'coz that will cause a lean condition too.Good Luck
