Do you know the H/L settings you are using on the GT 33? I find their manual a little confusing. Also, what oil and ratio do you run? The manual says 50:1 in one place and then recommends 25:1 during break in. I've never seen that before. My DA engines don't require any additional break-in and they say to bolt and fly. And they just do-even when set from the factory a little rich. I just don't have to mess with them all the time and I know they won't die on me. The GT 33's I've seen need constant tweaking.
