I have an early 80's Johnson 2hp. I can't remember how to start it with all the knobs on the front. It's 100/1 fuel. Can someone post a pic. of the front and tell me what to use. It has two knobs. And a small switch on the left side, real small.Thx, Dave
If the decals say 100:1 then it is a 1985 model. Before that it would have been 50:1. and AFAIK there were no 2 hp models after 1985;
However a couple of years later they switched all of them back to 50:1 again including those already sold as 100:1 motors.
The 100:1 decals should have been removed and the manual amended accordingly.
The model number will identify the year for certain. (J2RCOC will be the number for 1985. Check it and post the number if different)
The knob which pulls in and out is the choke. The other two knobs are the mixture adjustments, The top one is the idle mixture and the lower one is the high speed mixture. If the carb has been correctly adjusted they should both be set to their mid points.
If necessary to adjust the carb see Joe Reeves' instructions via the "Top Secret File" sticky on this board
The knobs #13 are the mixture adjusting knobs. The choke is #7
Set the throttle to "start" ( a bit more that than 1/2 way to being fully open) The mixture knobs as above and pull the choke out fully, As soon as it fires you'll probably need to get the choke back part way until it warms up. Then pushed back in fully
