  1. I have sent you a note
  2. It’s always difficult giving a diagnosis without actually seeing it, however when you say new carb is that from another saw or a new carb that a dealer has correctly entered the firmware ? ( all new auto tune carbs come with just boot firmware ), now does it have the orange frame air filter? these filters block very easily even though they look clean so make sure it is very clean, a pressure test would be my next thing to do, if you could get it plugged into cst it would give some clues by looking at the fuel settings, unfortunately any loss of compression will effect the idle, so is it mechanically sound ( seized, ring wear etc ) things like plug change and fuel filter change should always be tried as this is easy to do. It goes without saying that these machines rely completely on cooling air entering via the starter housing grill to cool the engine, so keep all openings free from blockage ( additional heat will effect running and hot restarting ). Leakage from the deco valve will also effect idle, I have blanked deco valves off in some cases.

    Husqvarna 40

    Yes I would start with clutch springs, with the clutch off, if you open the shoes with your hands the springs are shot, other than that if the drum bearing is badly worn the brake band will pull the drum to one side allowing it to rub on the clutch causing it to stop.
  4. I was told not so I guess that is it.
  5. With the greatest of respect there should be no need to keep adjusting carb screws, having to adjust the mixture is very often masking engine issues, auto tune is very reliable, it will keep the saw running at peak performance without the need to fiddle with adjuster screws, one of the main reasons I see is users ordering new auto tune carbs from dealers then find they do not run as they only have boot firmware on them, then they need to be connected to the service program.
  6. Went through something like this a few years ago with a hedge trimmer that you could not tighten the blades ( shoulder bolts through the blades) the blades then tear the the non woody spindly parts of the hedge rather than clean cut it.
  7. The Husqvarna electric saws were always built in Norway, I am pretty sure they are not Makita machines badged engendered, however I will find out for sure.
  8. You may struggle to get genuine fuel/oil caps for the 40, the early saw had smaller caps than the later machine and are definitely no longer available , the bigger caps may also be unavailable.
  9. Glad he worked it out, I knew it would fit.
  10. That is the blanking plate for the inlet, I have used it many times, how on earth are you trying to fit it???
  11. You are quite correct, we had to stop using an electric saw on the test leg, due to the addition inertia of the heavy armature it could cut through the safety material.
  12. The answer is in the name, inertia, in early saws we had no brake, this moved on to a brake that did work by the hand guard hitting the back of the wrist if a kick back occurred, unfortunately in the felling position there is no way for the wrist to come in contact with the hand guard, so next stage was an automatic brake ( Swed o matic ) as Husqvarna called it, here the engine unit would move on the anti vib mounts and an adjustable button on the brake, or on the handle would actuate the brake, unfortunately this was dependent on correct adjustment, and anti vib mount condition, so the inertia brake was born, weights are set in the hand guard, now due to the veracity of the kick back the guard tries to stay still as the saw body moves back thus bringing the brake on, Husqvarna now have what we call a knee link inertia brake, probably one of the most reliable brake there is, there is also the trio brake, this is a third way to bring the brake on, fitted to the rear handle this combats what is known as a slow kick back where the chain can run up the limb with insufficient inertia to bring the brake on. So in my humble opinion the test in the video is absolutely correct, and should work with both petrol and electric/ battery machines. End of todays lesson and apologies if insult any bodies intelligence.
  13. I guess the Stiga is similar to the Husqvarna Rider which I am more familiar with, when you engage the pto you hear the cluck of the electromagnetic clutch engaging yes? is the bottom pulley now spinning? if yes then it has to be a belt tension issue, either with the belt from the pto pulley, or the belt on the top of the deck, the one on the deck will have a spring loaded tensioner, this may have become disconnected and no longer tensioning the belt.
  14. I always strip down, take pictures and send along with a cost to repair, this customer is an idiot he probably knows full well how much a dealer would charge him to do what you have done, charge him the cost of the parts and tell him to f k off and never darken your doorstep again, he may feel the guilt and pay the original price.
  15. Yes it could be the fuel hose has aged and become loose in the tank ( they are only an interference fit ) however the fuel tank breather is also along side of the hose, and if it’s a later saw with fuel purge there will be a fuel return hose as well on this side.
