Hi all.
I have the above noted motor, (J2RCNE).
My mother bought the motor new in 1982. It might have 50 hours on it and all the ignition parts look new. The motor hadn’t been run for at least 15 years but ran fine. 2 years ago I decided to get it running so I cleaned the carb and a rebuild kit. I made sure the points were set correctly and they were. Put fresh fuel at 50:1 and it fired up right away and ran great. I put it on a boat and went fishing. The motor slowly lost power and eventually wouldn’t start after 2 hours.
I was unable to work on it until now.
The trouble shooting started with spark. Good solid spark on old and new plug. Air ….to easy. Fuel. I unhooked fuel line and sprayed fuel in carb. Nothing. I was thinking fuel all along. Checked points and good at .020 on Tod mark. All the electronics on top end look new.
next was compression. I use a drill with a modified bit as an electric start. On slow, about the same as rope pull it was 90 psi and on fast, about 300 rpm it was 100 psi.
I have worked on many small engines in the bush where you gotta do what you gotta do with great success. I am working in my garage where I have all the amenities and this thing has me beat.
Any suggestions welcome.
