Got one that has us stumped. This is dads 8n. IT was rebuilt completely 2 or 3 years ago, and has ran perfect since. About 150 hours.
Now we are having what I believe is a fuel issue, but cannot put a finger on it.
The tractor starts up and runs just perfect. But after a few minutes, it will start running really rough, like it is starving for fuel. No power, cough, choke, etc. That will last anywhere from 5 seconds to 30 seconds. Then clear up and run perfect again for anywhere from 1 minute to 5 minutes and the issue happens again.
The timing isnt consistant. Sometimes it will go along time and not have an issue. Others, it seems it no more than clears up and it does it again. Also, sometimes it does it and comes out of it instantly, othertimes it will linger for a good 30 seconds and sometimes even die as a result.
Messing with the load screw on the carb anywhere from 1 turn out to 3 turns out and anywhere inbetween does nothing to help. Even pulling on the choke does nothing to help while it is acting up.
Coil and ignition parts are all new. Plugs are new. Getting good fuel flow to carb. and screen in the elbow is clean. Carb has been apart 3 or 4 times now and cleaned and all passages cleared with air. Last time we put in a comprehensive rebuild kit that included new jets, seats, seals, and whatnot.
Still doing it. Cant figure it out. He is bout to throw down ~$160 and just buy a complete carb to see if the issue goes away. But worried about spending that kind of money to not fix the issue if it is something else.
Anyone got any ideas?
