What to believe?

[2mate]

Well my 1998 evinrude 25 belece is confusing me. The choke enricher mounted to the side of the carb has a red valve which i am unaware of the positioning. The service manual says facing forward is the "Prime" position but when i have it in the run position the engine stalls. Is the service manual wrong? And the run position is at the front?
HELPPPP

Re: What to believe?

Time to check the fuel system, BC what you're describing is fuel starvation. The primer alleviates it but doesn't correct it. The manual is correct about the position. Either carb needs rebuilding or:

. air leak on pump suction side (bad clamp, cracked hose, cracked tank pickup tube, etc., etc.)
. malfunctioning anti-siphon valve
. plugged tank vent
. trash blocking tank pickup screen
. plugged fuel filter
. collapsed fuel line
. check fuel pump output by taking off outlet hose and cranking engine over (make sure it can't start). You should see long, strong pulses of fuel. If not, pump is bad.

Does it fail during warm up or all the time. It is not uncommon to have to give the primer a bump or two during warm up. First minute or so. Rick.
