OK, I may be in over my head...
I have a 1991 Johnson J40TLE that came with a pontoon that I'm trying to determine if its any good. It has compression but the cylinders are about 10 PSI apart.
The PO took off the VRO and hooked everything back up without a fuel pump. The controls were also disconnected.
Over the past week I bought and installed a new "regular" fuel pump, and the motor would start, but then would stall immediatly. I then took the carbs apart (they were filthy), soaked Overnight, removed and cleaned the orifice's, and tried again today.
It would start, but it would stall almost immediately without pumping the choke. I tried using the lever on on the controls to rev the engine but no luck. I finally just used the lever on the carb itself and was able to keep the engine running, but only at a fairly fast RPM, when I let it slow it would stall. I was afraid to keep it racing very long, and although it stayed running (about a minute), it was very rough.
Questions: What should I try next? I am guessing since I just attached the controls the idle is way off, so that may be part of it.
I am open to just about any suggestions.
Possibly unrelated question: I have no idea what the knobs on the controller under the key do. What are they and could they be involved?
