I have a J50TLCCS Johnson Outboard 50 1988. It has been out of the water for eight years. I started working on it again a few months ago. I got it to run after cleaning out the carbs (dual) and then fixing a lot of mechanical things like the tilt/trim motor. I put it in the water and I could not keep it running. Every time I tried to accelerate (really just apply any throttle) it lugged and died.
I brought it back home and rebuilt the carburetors, including replacing the high and low speed jets. It started fine but then seemed to die after idle for a while. Next I replaced the fuel pump and cleaned up some wiring (like what you see in the 2nd image), but I still have the same symptoms. It starts when cold, but will not stay running. If I throttle up it lugs and dies immediately. Earlier I thought this was just flooding so I bought the factory float gauge and checked the floats. They seem to be pretty good.
I'm running out of ideas. The two remaining are: 1. Flooding because the floats are still wrong. 2. Timing. I'm having problems figuring out how to get the timing set. My book doesn't seem to match whats on my engine. I'm attaching two images that make me think this module adjusts the timing. The first image is the front cover to the carbs. It shows the timing value (on the top middle) and an picture of the module (lower left of the cover) that led me to believe it might adjust the timing. The next image is the module itself.
I would appreciate any advice on what should be my next diagnostic approach. If I could get back in the water by this fall. Wow that would be a dream.
Thanks in advance.
