    [quote=Redback;849479]It is starting at the moment, i made up a new batch the other day, i'm going to do another batch a little leaner to see if it makes a difference.

    I think you're heading in the right direction here.

    Once you've got it running, you'll then need to tune it using both the high and low speed jets to eliminate the flatspot (you need a good ear for this to be able to pick when it starts to 'fourstroke') and you'll achieve the 'snap' acceleration.

    First thing i checked was the plug and the spark when i changed to the new plug.

    We'll just have to see how it goes over the next couple of camping trips.

    Thanks everyone.

    Yep have always done this, never done 50.1 but have always left the fuel in the saw between uses and never had a problem, but this saw is different for some reason, seems to be very sensitive to the slightess ratio change, which i have never struck in all the years of owning 2 stroke engined devices, i raced bikes for years and never had anything near the problems i'm having with this saw.

    Very frustrating

    try changing the fuel filter, even if it looks whistle clean.
    Other possibility is a pin hole in the fuel line - does it run better with a full tank of petrol and gets worse as the fuel level drops?

    Yes i did, especialy if it was a long track where you were flat out for long periods (ie) Oran Park, Eastern Creek, Bathurst.

    I seized my RZ250 at Oran Park right near the end of the straight, just got the clutch in before it locked the rear wheel up

    ive used LRH's shindiawa, it had just been serviced by his agent, dont know what oil mix it was but it wasnt right, just had no guts and made any job painfull. i gave it abit of a tweek (hi/lo mixtures) to suit the mix it had. that made it abit different. he didnt notice it as much as he was only cutting up pallets.

    only use premium fuel if the manual says so. premium WILL change the temperature of the cylinder and piston and can reduce compression.

    as for the plastic case stihl, stihl did this to lower the cost to target the home user not the professional. i would not hesitate to buy a cheaper stihl. the main bennifit it has over alloy is the acidic sap from palm's wont eat the case.

    you have seen how well the ms230 i have from work works, its 3yrs old now has plastic case and oiler and is abused by kiwi's coates hire had replaced their saws from the old 08S to the ms280.

    if all else fails and you have lost faith with your agent, you know where i live

    cheers phil

    Does it have cats?

    I've had similar problems with a Husqvarna 2stoke [brushcutter]. The newer Huskies have a cat that can become built up with carbon, it's essential to use the genuine "cat safe" oil and mix it pretty much bang on 50:1. It also doesn't like excessive idling or light work.

    I found that it became easier to start after 10 or so hours, and its now got about 25 hours on it and starts easily. So maybe it just needs more time to run in. I also give it a good flogging now, get the EGTs up to clear out the cats
