Float bowl needs to be pulled and checked for crud.

 

ok thanks

 

Ok, Cleaned out the bowl with new gaskets etc.....still have the same problem

 

My guess is the fuel pump may be going bad.

 

Possibly sucking air from someplace, maybe a bad gas line.

 

I had this problem, and it ended up that there was crud in the fuel line. Check the fuel filter to see if it is at least half-full of gas. If the filter doesn't have much gas in it, then not enough fuel is reaching the filter. Either the pump isn't working well or something is clogging the fuel line between the tank and the filter. It sounds to me like the carburetor isn't getting enough fuel from the bowl, and choking the engine gives it enough fuel to keep running (but with no power, right?).

I would check the fuel pump and the fuel line, as well as the fuel filter. Also, this could happen if there is water in the tank or carb bowl.

 

Yeah well I took it apart again and the was a small amount of crud in the hole where the needle seats, I had blown it out but I guess it wasn't enough gonna try it again tomorrow

Thanks for the replies

I have a similar issue w/ my x300. It runs rough at low RPM. It lopes. At full throttle it runs fine.
I have done the following:
Adjusted the valves. (engine has ~ 280 hrs on it)
Checked fuel filter. It's free & clear. When running, the filter has plenty of fuel in it.
Blew air from fuel filter into the fuel tank. So that line should be clear.
Checked plugs. The look fine. Not lean and not carbined up.
Tried adjusting the carb. But the adjustment screws didn't have much effect.
Cleaned the air filter.
I don't know if the fuel pump is working properly. Don't know how to check it.

If anyone has suggestions, I'd love to hear them.

 

Solved my problem yesterday. I pulled the carb and cleaned it. Now the tractor runs much better. Hard to believe that w/ only 280 hrs the carb would get trash in it. I'm guessing it's the Ethenel (sp) gas. I use Sta-Bil. I guess now I'll have to add a little carb cleaner each spring.
