Hi
I'm new to gas powered planes. Just got the 35cc 260 from Areoworks. I'm about to order a DLE55, probably from ValleyView RC. I've been reading quite a lot on this forum and I've got a question. I've seen the term "burble, gurgle, and gerbil (well not gerbil) and I'm not sure what these terms mean in regards to the engine. Is burbling and gurgling interchangeable words to describe a sort of hesitation in the engine as it revs up? I'm guessing that is what it means. If not, what sound do I listen for to identify burbling or gurgling and how is this problem fixed.
Thanks in advance.

Mike
