.....1234, Sounds like the 1" tall Bermuda golf turf is the best case possible for flying off grass with the 40LA powered Cub. That's good. Now on the fuel valve/fuel dot question......John and don't see eye to eye on that question. If I remember right we went back and forth with each other on another thread arguing the merits of each system and finely had to "agree to disagree" on that one. He hates fuel valves and I do use them and defended them. On a Cub I just restored for a club mate it already had a 3 line system in it that we were going to reuse so it was an opportunity to try a dot (remembering my debate with John as i did it). The plane owner supplied a nice machined aluminum mounting dot and plug. Well, I LIKED IT!! So maybe John won that debate in the long run. It did make for a nice easy to use good looking installation. I still remain a user of valves but am open to trying the dot again in the future. I guess it is a matter of personal preference. Try both and decide for yourself. Jester-s1 ("stab a screw in there and keep on flying") is my "old screw works" example. Yes, it works but I like to do things certain ways, personal preference again (or picky old fart??). Pick your poison! Both Jester-s1 and John Buckner are great sources of information and I respect both of them, it's just that on some things we find different ways to get to similar end goals. I have had a fuel valve fail on me at the field only 2 times and I use quite a few of them. Once It stuck open and I couldn't get the engine to start till I noticed the valve core not in correct position. On another plane at a fly in one stuck open and leaked out the fuel as soon as I unpluged the fuel probe. Couldn't get it to seat and in both cases I just put that plane back in the truck and flew something else that day. I replaced the bad valves back at the shop, not a big deal for me. I think that the "o" rings inside expand with age and then the valve gives trouble. I have never had one create a poor running engine or a dead stick in the air, but maybe that's possible. For me they either worked or they didn't and it leaked. Doesn't happen often but it does happen after they are a few years old. I know John is following this thread and I have a question for him......with the simple split in the carb line for a fueling line as you describe on a 2 line system how does the carb not get flooded as you are pumping in the fuel. It's going to go both to the fuel tank and the carb in equal amounts isn't it? What am I missing?
