Many thanks for your replies. The fibre breather must have dropped of at some time. No leaks from the fuel hoses all replaced, I could see fuel pouring out from the plastic nipple.

My 350 has been leaking fuel when on its side. After dismantling I noticed what appears to be a small breather on the fuel tank that is letting fuel out. Should this have a breather tube or perhaps a non return valve attached. Many thanks for any help

No, plug completely dry, no fuel even rises from the tank to the carb. Thanks for continued interest

Thanks for the replies, much appreciated. I used a car type compression tester so the CR could be higher than 125 PSI. On removing the exhaust box the piston looks fine no scoring just a nice shiny piston. Perhaps back to the carb, the replacement was a Chinese copy. Placing a thumb over the inlet manifold and pulling the starter cord I could not feel any suction, perhaps this is not a good test?

Thanks for all the replies. I do also own a 365, a big heavy beast ( for me) and that seems to be far better constructed. I was comparing the 113 with the 350 as they both cost me similar amounts albeit a few years apart. What puzzles me is that the 350 saw seized several years ago and following excellent advice on here I replaced the piston and it has performed very well for a few years. The compression only measured 125 PSI after the new piston but it started instantly. I gather that 125 is very low, perhaps I was lucky. If the compression is low how come it starts instantly with Easy start? And revs very freely for a few seconds.

Thanks Spudulike, You are correct no input gasket. It is a 350. My confusion arose as I recently fettled a very old ( 35 years) Sachs Dolmar 113, it needed new carb parts. That did have an input gasket. What struck me was the far superior (IMHO) construction of the old Sachs Dolmar, decent Duralamin where Husqvarna use plastic, even the crankcase on the 350 is plastic. Yes the 350 is much lighter but not half as durable as the old 113. I know which one will still be around in 10 years! The 350 is already showing signs of age with screw threads worn and cracked plastic.

Thanks for your replies. It only runs for a short burst on easy start just for a few seconds. It was running just fine on 125lbs/in2 and has been for several weeks. No fuel is being sucked up from the tank, all fuel lines are free.

My 350 has been running well but suddenly cut out and would not restart. A good spark, good compression 125 lbs in2. Fuel not being drawn into the carburettor. Replaced the carburettor but still not drawing fuel. New fuel lines and tank filter, It starts OK with an injection of easy start . It seems as though there is no vacuum from the cylinder getting through to the carburettor. I have checked that the input gaskets are not blocking the inlet port. Any ideas? Thanks Paul

Spudulike, A belated big thank you for your advice given many moons ago regarding a scored Husky 350. Did as you said and cleaned up the bore, fitted new piston etc. Started first pull. Great advice! Have now got a spare saw.

Thanks Lillywhite Timber, I tried your suggestion of leaning over the tree and starting the saw nearly vertical, and when completed it made a perfect cut with no annoying wedge. Perhaps a longer bar say 24" would make life a bit easier as has been pointed out by CJ the effective length of a 20" bar is only 18" with the dogs on. Thanks all for the most helpful replies

Many thanks for all the replies. Not only was the chain new so was the bar and the saw. My first cuts since buying the 365 last week. It must be my technique. As one cut was fine the problem was the other 20! Being an irregular user I have had no problems in the past with smaller trees but this one has proved difficult. The tree is far too large to roll over but fortunately it has fallen on many smaller branches and intentionally placed posts so was off the ground for most of its length. Maybe putting too much pressure on the saw instead of letting it do the work, Still some more to cut so will take on board your advice and try again. I feel I cannot contribute much on here, anyone having problems with old cars, I know a little bit more about them! Bertram Hill - Home Thanks again, Great Forum !

Hot sure if this post is in the correct section but anyway: While sawing a 3ft diameter trunk into usable chunks with a 20" bar for splitting I find it extremely difficult to match the cuts from each side to give a clean cut, usually I finish up with the cuts not meeting at the bottom sometimes by a large mount necessitating levering the chunk off with a wedge or more usually a crow bar. This even occurs with a brand new chain so I must be doing something wrong. Would a larger bar say 24" make it easier. The saw is a Husky 365 so plenty of power. Any tips much appreciated.

Many thanks for all the helpful replies, what a great Forum this is! There is certainly some scoring of the bore and piston but it does not look too bad. The seal between the crankcase and the plastic base looked decidedly rough with evidence of oil tracking across so perhaps this was the reason for the seize. I did notice on the day before the seize that the saw was hunting on full revs, perhaps an indication of an air leak and weak mixture. What is the best sealant to use between crankcase and plastic base, is ordinary silicon sealant adequate or does it need something special? Thanks again.

Many thanks " Cut4fun" for your most comprehensive reply with excellent links. The Carb linkage is the later version with the steel clip and is OK. I have since checked the compression and it measured only 50 psi so looks like the saw seized and caused the problem. Wonder if its even worth considering replacing the cylinder/piston as the saw is 8 years old.

My Husky 350 has been used for general farm tree work a few times a year for about 8 years and has performed faultlessly. While sawing a fairly large poplar the saw suddenly stopped and smoke was seen coming from the starter area and it could not be restarted. Suspecting the ignition amp had packed in I tried a new one but it made no difference. Stripping down the engine I could not see any problems, resealed the crankcase cylinder seal and tried to restart. Not even any attempt to start. There is a spark and fuel appears to be getting to the cylinder. I am completely baffled. I will be buying a 365 but would like to keep the 350 for lighter work Any suggestions much appreciated.
