I am working on a JD RX75. The motor starts and runs beautiful for about 1 minute, then dies. It starts right back up and runs for a minute and dies. What could be the problem? I am baffled. Please HELP. Thank you. Please contact me via email, tglawman@bellsouth.net
It could be that there is poor flow of fuel to the carb itself. It runs itself out of fuel in the bowl and dies. I would check that the fuel shut off is open and good flow first. Fuel pump on these? Try it w/ the fuel cap loose to ensure it is venting. A can of carb spray would be useful. If you go this far and still not running, a squirt down the throat of the carb as it is dying would tell you if you still have spark anyways and would indicate you need to go further w/ the fuel system. There could be other issues pertaining to ignition as well. Let us know what you learn.
I have totally cleaned the carb., bowl was little trashy. replaced all fuel line, fuel shut off is working as it should, cleaned the fuel tank, lots of trash in it. I am replacing the air filter and spark plug this week. I also replaced the ignition relay, that turned out to not be the problem. It has to be in the fuel system. No fuel pump on this one. from tank to carb. i will let you know hot it turns out tomplum, thank you very much for your assistance.
