Wow, that was quite a read. First off, I want to thank all of the contributers to this thread. I think I'm going to try to do a conversion on my Saito .82. Do you think the Zama (or walbro) mentioned would work with the .82? Assuming I can find either... I'll also be keeping an eye on your CH site, Adrian, for when you start to sell the ignitions again. I may buy one of the other Zama carbs on e-bay that I've seen, even if it won't work for the .82, just to get a better handle on how they work. Maybe I'll try to figure a way to regulate the fuel so that the stock glow carb will work. It sounds like less fuel is needed in the middle. Maybe play with needle taper. The stock needle has a very linear taper which can be changed easily enough, and I have a Cline I can play with. I must admit that I love messing with these small engines. If I get it to run well, I may have to get a plane to fly it in!
