RE: DLE 20.....very hard to start (80+ flips)
I guess for me it is a pride thing. I hate to have to turn to an electric starter. One of the things that the guys at th field know it that my engines start easy and quickly no matter how long it has been since I have brought a plane out and I struggle with the rudder. Lol. (Another story). I feel that if the engine is tuned right I only need to flip it. So far so good. I will say that I have found that on the engines larger than the 30 dle you probably don't need to solder the carb. I just do as a part of my set up. And as for Walbro knowing more than we do, yes you might be right but I bet they never envisioned there carbs being used on rc airplanes. But as has been stated to each there own. I prefer less equipment at the field and an easy to start engine helps.
