Hey guys 89P 980B 1975 (forgot this ones serial # maybe 3000) It's used for snowplowing mostly. It loses prime after sitting for a long time. Sometimes its fine for a week or a year and then it creeps up again. It fires up but fuel pressure drops right off and it stalls. Pump up the primer and it's good to go. I've tried to chase this down before but' it fixes itself before I do. No rhyme or reason two winters ago I had to prime it everytime, last winter and this summer it never happened. This week it's back any Ideas? Thanks Randy
