G'day Now that you mention it, my ancient Enya 46 4c sounds like that at idle (without a muffler). Makes a sort of "ploip ploip - ploip" sound. Mike
He he, my friend yallaair`s Enya 120 also sound like that at idle without the muffler and pipe. We used to describe the unique sound as like a aquarium pump (you know the pump that pumps airbubbles into a fishtank) Very funny sound from such a big engine[sm=lol.gif][sm=lol.gif]
