OK, I’m a complete moron the other day. I thought I smelled some fuel in the garage so I decided to turn the fuel shut off off on a Massey Ferguson model 35 industrial tractor well I accidentally adjusted the main discharge jet and now I don’t know what it’s supposed to be set to in the tractor will not start. I tried tightening it all the way down and backing off a quarter turn at the time and seeing if the tractor would start, but it won’t it. The other weird thing is that when I backed it all the way out there was no fuel coming out of the hole. I feel like a moron. I can’t believe I did this. The tractor ran great now. I don’t know where to start any help that can be provided would be greatly appreciated. Thank you.
