Reply To: 1933 Johnson J-65 restoration questions

This is the third time I’ve tired to post today and they won’t stick. Perhaps it’s because I tried to post photos…very confusing.

I got the Johnson started today. I found the fine tuning jet on the carb to be very sensitive. a 1/16 turn either way and it’d start to kill. But in the sweet spot it ran strong. I had it on a stand with the power shaft down in a garbage can full of water, no prop, obviously.  Shortly, I noticed a minimal amount of water dribbling out of the orifice on the shaft. The engine was heating up so I shut it off.

I pulled the pump and took it apart. Seemed pretty clean. The pump cylinder and spring worked well and weren’t binding. The cylinder was in good shape with no holes or problems. The check valves were clean and seemed to be free motion. The only thing I saw was that someone soldered in the screen at the bottom of the intake on the pump and got a little too aggressive with the solder, probably plugging up 25% of the area.  I tried blowing and shooting air through the water channels and it seemed to go, but I wasn’t sure. Key question: Do they or the water channels in the head plug up often? None of the tubes were kinked, but at least this morning there wasn’t enough cooling.

 

I’ll try to post some pictures in a subsequent posting, but in the last three tries that has been the kiss of death for the whole thing.
