It's taken me around 25 years to come to the realizations and experiences in the old noggan. I have a fascination for engines and carbeuration and tend to spend countless hours getting glo engines just right. After that I just concentrate on something else and fly like a whirling dirvish This however will be my first season flying gas. I have a 3W 80 in a 33% Edge 540T. What are the kinds of things that ruin your day with gas engines, 3W in particular? I guess the carb and it's associated parts would be a culprit at times. What are your experiences?
Take care and come on spring_Bob

I,ll start the fun on this one with a big IMO.
I also enjoy the engine side of things,but have switched over to gas almost totally.(OS 90 4 stroke,ZDZ 60cc,Quadra 400 coil,Quadra 400 electronic,two Ryobis at the moment)
With proper fuel set up with no air or fuel leaks,and filters in your fuel storage and plane tanks,the truth is you almost never have problems with a gasser at least in the normal applications most of us use.It is futile and normally unecessary to play with the carb needles once you have a little time on the engine,and have settled on an oil type and starting drill that works for you.You will get to know your engine very well,and given some problem the cause is usually very clear.
Some will enjoy modifying the engine for more performance,which is another total ball game,and brings its own problems and rewards,but it amazes me how many really uninformed owners try these mods without the necessary knowledge.
You can also get into serious arguments about things like velocity stacks,and prop sizes and types for example,but I think you will do best to get some flying time on your combination then experiment,when you are better able to judge resutls.......

My $C .04 worth

Can't wait to get some time on this set up. I've always wanted a large scale and this is my year
