I have a problem on my suzuki dt 85 outboard. it runs like a bat out of hell as long as i pump the primer bulb. if i stop however, i the engine will bog down as if it's fuel starved.
get this though: I've changed out the diaphram kit in the fuel pump, cleaned the fuel filter and it has good gas.
what gives? the only thing i can think of are the little o rings between the fuel pump and engine block. i don't see any visable cracks in the fuel line and i've changed out a leaking nipple/ quick connect on the engine cover.
the o rings look good but maybe at high pressure they are leaking being that they are hardened after 30 years???? do i need to change out the fuel filter o ring also? the fuel pump seems to be pumping fine but maybe it's sucking in some air somewhere right???

any suggestions guys and gals? thanks, ken
