RE: Timing question
Most engines run it at 28deg BTDC. You will need a degree wheel and check and reset if reguired. Won't let me upload the PDF. Can be found at http://www.dlenginesaustralia.com/dl...iewDoc&docId=9 half way down under Ign Systems- Ing Installation

Mine turns a Zoar 14 x 6 at 10,600 rpms. About 12.5 lbs static thrust. It was converted to roller bearings for me by Keith at BME and I run it on 20:1 oil. (Actually I got those numbers after only one tank of fuel through it. It might be turning a little more now.)
BME offers them converted, as well as www.lambertsrc.com

RE: Timing question
I have a feeling mine might do 11,000 rpm on a 15x4 currently as a glow engine, but the carb has to be retuned after a while of sitting. I think that a spark conversion will help. At least there wont be as much oil mess.

Your answer raises a question. There is a notable performance loss between a 40:1 and 32:1 so how much more loss at 16:1?

performance loss between 32:1 and 40:1 ????????? maybe you just needed to retune it. there is no power loss at these sorts of oil ratios in fact it can even be argued you will gain power...... search for gordon jennings more is less less is more etc etc article. I have tested from 30:1 to 50:1 ratios and ended up now on always running 35:1 from run -in and always..... its a very debatable topic, but power loss is not a good argument...
