yea, the settings can be confusing. For the CO3 the glow plug and gas settings are controlling the pulse off time, thus the higher the number the less power. But Start PW and Prime PW control the on time, so bigger numbers are more power. For the CO3 the way I remember it is that if you need to make an adjustment to correct for large changes in air temp, the settings for glow and gas follow the temp. On hotter days you need less gas and glow so you can take the values up to extend plug life. On cold days you need more gas and more plug to light off so you move the values down. Actually the reason that the gas needs adjustment is that its pressure, and thus flow rate, changes with temp. Which brings up another subject; if you have just filled the gas bottle it is probably cold, thus the gas will not flow as well. Warm the bottle up with your hand before you try to start.

The final settings will vary a lot depending on how long all the tubing is and how constricting the fuel tanks are. So unfortunataly there is no one setting that always gets it done.

The newest version of the Bob Price ECU has all the values as voltage now; much easier to follow. It also has some other nice improvements.
