Hi<br /><br />My yamaha have this wisseling sound and I've been told that this is because the carburettors need to be adjusted.<br />Does anyone have the data for the adjustments needed.<br /><br />thanks in advance
Hi Skiboy,<br /><br />You will probably get a reply if you post this question on the "Engines and Motors" board. I too have a Yammie 40 but have not had the problem (yet). But I'm curious to see if anyone else has.<br />By the way, what tune does your engine whistle?
