25:1 always, although Hemistorm Chris recommends using a higher ratio of oil so the engine has an easier time breaking in.
Here is the link for the Octane Running Tips PDF which has all the details for breaking in, tuning, troubleshooting and even testing the CDI unit, which many people seem to blame for the running issues:
http://www.hpiracing.com/assets/docu...nning_tips.pdf it seems the problems come mostly from not breaking in the engine long enough (20+ tanks and you will start seeing the engine get more and more powerful), dead spark plug, bad spark plug gap and also 'tuning' the engine way too much.
