ADJUSTING POSITION OF SOLENOID - MODEL RDE
Original Johnson factory photograph showing RDE choke solenoid and carburetor adjustment

There may be occasion to detach the choke solenoid from the carburetor body of the Model RDE. When replacing, be reminded that some adjustment of its position is required when re-located for normal operation.

"See" that all linkage with the choke has been properly connected - greased as preventative against corrosion and resultant faulty action. Attach band holding the solenoid fast to the carburetor body, but do not tighten for the moment.

To position solenoid - pull manual choke knob out to full choke position. Slide solenoid forward until it stops against the solenoid plunger and tighten yoke screws.

Please take note - for future reference when necessary.

Yours very truly,
