2002 50 hp Johnson 2 cycle
It got so it would not idle without stalling. I borrowed a pontoon trailer and pulled it out. The marine
mechanics in Hartwell are 6 weeks behind so I tackled it myself. Pulled carbs off and put in rebuild
kits. Replaced all hoses on fuel/oil pump. New plugs. When I started it on land it ran good but would
not idle less than 1200 rpm's. The idle screws are back at 2 full turns out as they were when I pulled
carbs. Not sure what spec's are.
It ran good first time out and ran smoothly at 5100 rpm and 2000 rpm, but when I tried to
dock and put in neutral it stalled. Would only start with advanced throttle but would not go
low enough to put in gear. After much effort I was able to start and slam in forward tied to the dock..ran great at 2000-3000 but once I hit neutral it went down to 1200 rpm and would stall. Hard to restart
and only out of gear at advanced throttle and with some surging from 2000-4000. Tank bulb remains
firm and I see fuel in filter so it is getting gas. This motor always started hard . Any thoughts
on possible fixes:
air leak
fuel hose problem
low speed needle adjustment
throttle linkage issue
Floats?
ANY help would be greatly appreciated. I need to get a service manual soon. This all started after the repair
on its maiden voyage as I returned to the dock and tried to idle.
Thanks for any help or advice you can give me. Don
