1987 evinrude 60 fuel problem

[lostitnutter]

model BE60TLCUC<br /><br />engine goes great from cold, once warmed up runs fine until i reduce the throttle then it wont pick up again. primer goes soft (does'nt help if primer is pumped up again) pressing the choke sorts it out again until reducing the throttle then same problem happens.<br />i have disconected vro and am using premix, have rebuilt the fuel pump, and cleaned the carbs twice and replaced plugs.<br />compression test ok<br /><br />should primer stay hard at all times?<br />

Might have a weak fuel pump due to leaking pulse hose, diaphragm pierced or leaking fuel lines. At lower revs it seems that it just does not pump enough fuel. Once at higher revs via primer, the pump pressure is adequate to maintain rpm's

Hey lost....<br /><br />After the inital priming of the fuel system, the primer bulb will be soft after the engine is started and is running.<br /><br />Sounds like a vac. leak to the fuel pump to me. Curious as to the fuel pump rebuild. Usually when the VRO is disconnected, all that needs done is to disconnect the oil line from the engine and cap the connection on the lower engine pan. What did you rebuild?<br /><br />Thanks.

thanks for the quick replys<br /><br />fuel pump was rebuilt yesterday morning both fuel diaphram and airmotor diaphram, have checked pulse hose that is ok<br /><br />fitted a new plug on engine end of fuel line, does not seem to be a very tight fit would this cause the problem?<br />
