My tractor runs fine at low and mid throttle. But if put it up to full throttle, it wants to die. If pull choke out half way, it runs fine again. I've used carb cleaner ' spray ' in the past when I've had similar problems , and it works for a while , but , the problem always seems to come back.
Any suggestions?
