Makita Dpc6400 Stone Saw Disc Cutter 2 Stroke spares or repairs

makita dpc6400 disc cutter / stone saw. starts, runs and cuts. comes with a metal cutting blade that has done very little. water suppressor system will want looking at if this is required but does come with the saw. fairly recent air filter and plug. update: I was using the saw this weekend 22/03 and it was bogging out under load when warm, it still starts, runs and works for around 5 mins before this happens leave it a couple of minutes and it will start again? may be a fuel related issue or even a coil breaking down under load? I have amended the price to allow for further investigation.
