av8tor1977,

Mine is using a CH Ignition and I set the timing at 30 deg BTDC as a starting point. I had planned on trying to advance it between 30-35 deg as the engine was well used in it's previous life. I would like to thank you for all the help you have given me as it really helped. I have been doing alot of my testing of the engine at the race shop owned by the company I work for. One of the crew members was interested in helping me and he also was having fun seeing the results. He used to work on general aviation planes like the Sea Furry and he told me he was very close to purchasing an AT-6 at one time. Some of the other crew members seem to think I should be able to get more out of the engine by making some modifications to the piston and the cylinder as well as trying to make a "tuned" muffler. I have the time and the engines to tinker with so maybe those guys can help me with making a super weedie conversion....LOL. As I stated earlier I have a 30cc Homie and today I just received a 32cc Mac from co-worker who closed his garage door on the shaft of his fairly new weed wacker which he was going to throw away. I'll probably work with those two engine on magnito but I could also use the ignition from the 25 Homie on the 30 Homie if I wanted. The problem with having all these engines is finding suitable planes to put them in. I've done some research that indicates a 1/4 Cub is probably as good a choice as any for weedie conversions. Something that I would like to investigate and I'm sure you could give me a good opinion would be to find a smaller engine 16-18cc, trim it really good, add a CH Ignition and hang it on the Space Walker ARF from Great Planes. What do you think about that combo? (I know you have a 16cc engine that you had success with at lower elevations.)

Thanks
