Hard To Pump Stihl Sg 20
My backpack spayer is very hard to pump. The pump cylinder is clean and there is no corrosion. I have replaced o ring and felt thinking the old ones were causing the binding. Still hard to pump and black cap at top of pump will not stay in position. Ive owned it 3 yrs and it has been a good sprayer. Thank you in advance Joe
