I have a '85 6 H.P. Johnson, it says to mix gas to a 100/1 mixture which I know that this is to thin. Many people have told me to run it any where from 35/1 to 60/1. I have been running it at 50/1 just like the 30 H.P. I have. If you could let me know what is a good mixture to run I would appreciate it.
