Can someone tell me the best mix ratio glow/gas? I have an older quadra 35 that runs great on gas but have tried some of these mixes with no luck.Iwas using a starter but could only get intermitent very short runs.It has to be fuel mix because varied carb settings and types of glow plugs did not help? I thought I had screwed something up went back to original settings and gas and runs fine? any help would be greatly appreciated. Right now this is more work than fun!
