I have a 1984 Sea-Horse 2HP outboard motor (J2RCRS) that I purchased in March of this year (2014) and it ran fine at that time when I tested it in a 32 gallon bucket. After letting it sit for 2 months, I decided to bring it to the lake for a trial run. Of course I checked the fuel level in the tank first and since there was very little, I made up a 50:1 mixture and added it. When I got down to the lake, the motor would not start.
I thought the trouble might be old gas and/or poor gas/oil mixture so I drained the old fuel from the tank and from the float bowl, replaced the fuel line, replaced the shut-off valve and filter and added TruFuel (no ethanol, 92 octane, 50:1 gas/oil) and lo and behold, it started on about the third pull.
My issue now is that it seems to run very rough and when I turn the throttle past START to SLOW, the engine dies. I'm hoping that it is due to the 92 octane mixture and that I just need to perform a synchronization adjustment on it, which is where I would appreciate some help. I do want to note that, in the process of troubleshooting, I did squirt a little Pyroil Starting Fluid into the carb throat so I hope I did not screw anything up by doing that.
I know that I need to start with the high-speed needle first, then adjust the low-speed needle and go back to the high-speed needle but I do have a few questions. The manual says to line up the "roller" (on the cam follower) with the 2 marks on the throttle cam. I can see the 2 marks but there is no "roller" just a piece of plastic (or some type of composite) attached to the cam follower that presses against the cam. The plastic comes into contact with the cam when the throttle is a little past the START position. The parts diagram distinctly shows a "roller" on the cam follower.
My questions are:
Since the "roller" appears to have been modified, should I replace the plastic with an actual "roller" (the motor was running ok when I purchased it)?
Is the 92 octane mixture causing a synch issue?
If synch is the issue, can I perform this adjustment in a test bucket or do I need to install the motor on my boat and adjust on the water?
If I can perform the synch adjustment in a test bucket, where can I get a test wheel to replace the prop (can I fabricate one out of an old prop?) so that I can adjust at full throttle without the water surging out of the bucket?
Any help is much appreciated.
