I haven't gone by the book for years when it comes to two banger carbs so here is what I do. Open both needles about a turn and a half, maybe two turns on the load (inside closest to the fan shaft) needle. Play with the idle needle till it idles real slow. It's hard to judge RPM's but 400 RPM's is good and slow. Do this by playing with the throttle shaft on the carb to adjust engine speed as you mess with the needle or you can reach up and pull or push the hand throttle if you are tall and have long arms. If it dies while you are adjusting, start it back up, maybe with a little choke, and try again. You will be surprised how slow it will run before it gives up the ghost providing the carb is good and clean. Just keep playing with it. After you have it set to idle slow and easy, idle it way down, then crack the throttle open real quick. If the engine hesitates before it picks up speed open the load needle a quarter turn, return it to low idle, crack the throttle open quick and see what it does. Once you get it to accelerate quickly without hesitation you are close to having it right. Now, after all this is done play with the idle screw again to see if it changed or not.
This gets you close on the load adjustment and the idle should be OK without messing with it again. Best way to set the load screw is with it pulling hard on a dyno but not all of us have that luxury. Remember, a two banger Deere does not have to be run fast. You will have decent power for getting the tractor rolling and in motion with the throttle just above an idle. When you shut it down, pull the throttle way back to slow idle before you kill the engine. You will get the hang of it real quick.

Today's Featured Article - When Push Comes to Shove - by Dave Patterson. When I was a “kid” (still am to a deree) about two I guess, my parents couldn’t find me one day. They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
