roughly 3 years ago i had a demo on a salcombe flyer 530 with a 5 hour old 115 e tec, well i never actually got to go on it as it refused to start and when it did, chucked out a load of blue smoke and sounded rougher than a 500 norton!!
then the following weekend, i met the chap again, spanking new engine on it which would have come in on the deal, temp -2 ,two stroke oil refused to mix with fuel, No start!! would only run up to 1000 rpm or something like that,
laughably he said,
its never done this before
i wonder if the sales people are trained to say this in the event of any issues.
anyway , sorry going off on one....if the mains are outside their tolerance then replacement is the only option,whats the warranty on them??
all engine have their faults but these things are having the lions share at the moment, chris will probally help you on this one,
