Have a 07 660 with 1800 miles. Long story short ive had it 6 months, its just used around the our house and is our plow for the winter. It started to overheat so I put in a new radiator and decided to also pull the carb at the same time to give it a cleaning. Did so, put it all back together and now no start just cranks. Checked fuel filter, checked spark, all good. I tried cranking quite a bit and holding my hand over intake but still no start. Pulled inlet line to carb and filled it with gas and she fired right up run till line dries up. If the system wont prime should I assume my fuel pump is dead?
