Hi Gents,
Some advise please.
Johnson 15hp Belgium 1992
Recently out on the water - motor cold, motor starts second pull, need to play with choke until warm & pickup speed - then runs fine.
After running for a while, slow down to idle it will stall.
Then need to use choke to start even though motor is warm.
Back in the tank now.
Starts and idle - bit roughly on no throttle,
if I throttle up, it will raise for couple of seconds then splutter & stall.
Either throttle back or choke at this time stops from stalling, I can get it to rev higher if I keep the choke on half.
Is it temperamental and taking a while to warm up?
Ive tried adjusting the lean/rich knob, but doesnt seem to have any affect, started with 1.5 turns from closed.
Same with the idle adjust on tiller (This thing is stupid - seems to turn without end in one direction)
Fuel bulb is full, a pump doesnt have any affect
Put into gear, it will splutter & stall unless I use half choke.
I dont think its fuel supply
Possibly Carb needs clean?
Need new plugs?
BTW
Fuel tank - my tank does not have the breather knob on cap.
I usually open the cap to let the pressure out once before going out.
The cap needs to be on tight during operation to keep the fuel pressure good - right?
Thanks in advance
Cheers.
(Belgium model has nearly no water out the telltale - water comes out exhaust and small hole bottom of leg)
Some advise please.
