My little JD 40 acts like it is running out of gas. After a couple of minutes, it'll start up and run again, but will soon die..... ..... .I believe the carburetor is running out of gas. It's a new rebuilt carb. Where do I need to set the float for this? Any hints and procedures would be most appreciated.

Bill, your problem doesn't sound like a float setting problem. ~Open the drain plug on the bottom of the carb & make sure you have a good stream of fuel flowing FOR AT LEAST 30 seconds. If not you have found your problem. If you don't have 30 seconds of fuel flow look for a restriction at the strainer, or tank outlet, or there is a little fuel screen in the carb inlet line fitting that might be plugged....

If it's like the carb on the model M, which I think it is, then it should be 1/4" from the carburator baseplate...

Don,

Bill is right for setting the float @ 1/4"...just make SURE that both the front and back ends of the float's bladder are BOTH @ 1/4"...then when you rejoin the bowl with the upper body, make sure do not push or bend the float. When the two are screwed together, you should be able to rotate your carb and hear the float shifting inside when repeatedly turning it right side up and up-side down...if you don't, you may want to open it back-up & measure the distance again, and/or see why the the float doesn't move freely.

Good luck,
tom
