carb trouble???

[Donsyl]

Okay guys i had this trouble before and i cleaned the carb and it ran well. Once and a while lately it sputters and stalls. When it sputters i pull the choke out and sometimes it will stay running but not so well. WHAT COULD BE THE TROUBLE NOW? Do i need a carb rebuild kit? i cant figure it out. I have taken off the tank and cleaned it. and i have also cleaned the carb again. It might run fine for a few minutes and then sputters. The gas cap is good, i have tried to lossen it when this problem occurs and it doesnt change. i am beside myself right now and really need to mow...thanks in advance....Don

What tractor?
Do you have a fuel filter? If not, splice one in.
Old fuel? And by today's standards that can be just weeks old.

You could have just a tiny piece of trash in a carb jet. That was VERY common in my 1872 for some reason. I could remove that carb, clean it and have it back on in like 10 minutes, I had to do it so often.

Could also be a small amount of water in the float bowl, not allowing gas to flow correctly. Also very common in the 1872 I had.

Quite aggrivating, isn't it? I am having this problem with a 45oo watt gen -set that I just bought from a friend. I wish it had electric start, to prevent all that yanking...

Diesel nut, that is what happens to mine i clean it out and then 10 or 15 min later it does it again. I did get a small piece of trash out of the hole where the little float valve is. It seems to run better right now, but i dont know for how long.

OP - remove carb - clean thoroughly - rebuild using rebuild kit. During cleaning, use a combo of magnifying glass, thin copper wire (like braided stranded wire), and compressed air. With magnifier, closely inspect each cleaned carb component to locate any smallpassages or orifices. Run copper wire thru to verify passages open. blow out with compressed air. Above all, work "clean" during this process. Just the smallest piece of trash in that carb can cause yer engine probs.
Also, replace all fuel lines, fuel filter from tank to carb. Old fuel lines can sluff off shards from inside walls and re-trash carb.
Good luck and also CLEAN GAS CAN before getting fresh fuel to re-fill tractor.
