400 versatile swather

[Moos]

I am having trouble with my 400, to keep it running. Seems to have something to do with the heat. Runs for so long, then just dies. Can start it back up immediately, and it will idle just fine. Throttle up, and it dies. Sometimes if I sit for a minute or so, then it works again. Sometimes for 20 minutes or so, sometimes 10 minutes. Runs perfectly when it runs. Thinking it has something to do with the fuel? Any help is greatly appreciated.

Check the fuel pump for flow .

Fuel pump was put on new 3 yrs ago. I don't do a lot of swathing. Put on new coil, new cap and rotor, and switched to electronic ignition. Still the same problem. Thanks

Tank not venting? try running with the cap loose.

Already have done that. Vent seems to work fine. Thanks

That means nothing. U need to remove the line from the carb and do a flow check by cranking the engine, it should shoot the gas out 3 ft. Why not do the check then come back and say yep. U want to get technical check the fuel pump pressure also. They both go hand in hand. U asked I give answer but it’s not confirmed so we need to wait more yet. Un used fuel
Pumps cause the most trouble.

Seen some place on a Thread where nobody posts after the problem is solved. Well, I am posting that I am fairly certain got my running problem solved. Ran it yesterday for about 3 1/2 hours, 80 degree heat. Ran fine. I replaced the rubber gas hose that runs from the tank to the fuel pump.

Thanks for the reply outcome, you’re right we spend time helping out but not too often hear what the fix was. I have the same swather also. Dam good units. And yes if that hose is old and rotten and collapsed and the fuel pump trying to suck fuel out of it is going to be a problem. Did u actually check your pump flow? Should be shooting out like 3’ .

I did not check that. May do that yet before I park it for the season.

Thanks for all the help. Is very frustrating when things don't work right.

That’s why I said check the flow , u would have found your problem right away. Always a reason for everything. U can’t suck fuel through a colapsed hose. Lol. No use doing it now if it’s running good. The other check is a pressure check on the fuel pump.
