I recently got my hands on a Johnson cj10rcue 9.9hp motor with accumix tank. I would like to convert to 15hp and use a normal tank and preferably a 50:1 mix instead of the 100:1 mixture the sticker on motor says. I suspect the carb has been messed with cause the choke don't close when you pull the knob out. so doing carb work either way.

Perhaps remove the choke knob and turn it 180 degrees and re-install.

I'll try that next time I'm out at the camper. I could close the carb by pushing on the butterfly valve. but would still like to upgrade this engine to 15hp.
