'07 Rhino 660 engine dying
Our Rhino is used for GPS soil testing in farm fields, it runs across the fields & stops to take samples. After the unit runs for awhile its dies, it seems to be when the air temperature is warm/hot. I have install new spark plug, clean air intake tract, clean the carb, & replaced the fuel filter. Then it ran for 7 hours with no problem. Then it started dying again, it does idle rough & when it runs it runs like new. Last year I put header heat tape to cut down the heat around the head pipe, because the dry cornstalk leaves catch fire on the head pipe. After the head pipe was wrapped with this tape it ran fine. It has been warm around here & it has ran fine for 2 weeks now it is acting up. I ran the rhino around the field for 1/2 hour then stopped & let it idle for 3 minutes then it would die. It never sputters it just dies from an idle, I can start it right back up. If I choke it, it starts right back up also, maybe a little easier then without it. I let the unit cool off for 3 hours & the air temperature drop down to 70 degrees, so then I drove it around for 1/2 hour then stopped & let it idle for ten minutes then it would die. I can start it back up & let run for a little bit then it will die again. Any ideas?
