Rancher TRX 350 FM Problems. Newbie here. My problems all began when my wife’s ATV didn’t get rode by her enough ….It started having gas blockage issues . I found the filter in the gas tank completely plugged up with varnish and i replaced it. I now had gas to the carb but still she wasnt right. After cleaning out the carb I got her to start and thought all was well..so I was test driving her and everything seemed fine ,steady idle, good acceleration and power. Then after about 10 miniutes she just quit. She ran fine until warm and then nothing . Would not start again until cold? Same thing starts right up cold and croaks as soon as she is warmed up? Any help would be much appreciated ….
