Ok

I have a Moloney 100 on a kit built Taube. I have pulled my hair out over a glitch problem. The plane has no problem while the engine is not runnig, but as soon as I get a few feet she starts glitching. I have checked just about everything I can think of and it still will glitch. It is a gas engine and has the old style magneto ignition. I think the only way to stop this is to change the ignition to cdi, but I hate to spend the extra $ if it is something else. Please help?
