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 - Old Time Threshing - by Anthony West. A lovely harvest evening late September 1947, I was a school boy, like all school boys I loved harvest time. The golden corn ripens well and early, the stoking, stacking,.... the drawing in with the tractors and trailers and a few buck rakes thrown in, and possibly a heavy horse. It would be a great day for the collies and the terrier dogs, rats and mice would be at the bottom of the stacks so the dogs, would have a busy time hunting and killing, all the corn was gathered and ricked in what we c
