    Chainsaw won't start

    The cylinder can be saved if it's not scored and only has ally fouling on it. Brick acid/patio cleaner wiped on with a cotton wool pad and long pliers will dissolve the ally without damaging the Nikasil lining. Then a quick scuff up with a bit of scotchbrite wrapped around a bolt in a battery drill will give it enough hatching to bed in a new ring and piston. Regarding Husqvarnas only running on a certain 2 stroke oil. It's to do with a clever idea called "oil gaurd" The K760 disc cutters are fitted with it. It's a small optical sensor in the fuel line, the genuine "oil gaurd" oil has a particular light refraction agent in it and if the sensor does not read it it will not energise the coil. It's there to stop moomins from chucking neat fuel in the saw and trashing it. The fact that Husqvarna have fitted a bypass tag that you just pull out so you can run standard oil is probably the reason there's so many on the sales sites for repair

    First things first, is there good compression? Quick field test is to place saw on floor and try to lift it by the pull start. Saw should lift from floor without pull cord coming out. If the saw starts to "bump" down the cord too fast remove spark plug and pull off the exhaust have a look in the port, and slowly pull the cord looking at the piston as it travels past the opening. If there is heavy scoring or blending of aluminium over the rings then it's time for a rebuild. Whilst the exhaust is off check to see that any spark arrestor fitted is not clogged. Next refit plug and spray a little fairy liquid around the decompression button and pull it over, any bubbles appearing mean a leak. After that assuming you have good compression try and start the saw, after ten or so pulls whip the plug out and have a look at it, is it wet or dry. If it's dry check the impulse line from the crankcase to carb for splits, any leak here will stop your carb from priming and therefore stop your fuel supply. As already mentioned a small squirt of fuel/brake cleaner down the carb throat and then pull it over will prove its a fueling issue. Also check your tank vent isn't clogged. If the plugs wet then check your carb settings, in to face and out 3/4 of a turn should get it fire and run with a bit of throttling. If not then you've deeper issues. Try it and let us know.

    Model of saw would help a lot. Early huskys are easy fixers, later stuff not so much.

    Chinese inverter welder

    Cast items can be a real case of Russian roulette, composition of the material will vary widely especially on stuff like garden furniture which will make appropriate rod selection difficult. You could opt for a dissimilar rod which will give you the best chance of a sound well fused weld, in order to avoid preheating use short 3/4 -1inch welds well peened in between and allow time to cool to the touch between runs, this will give you your best chance against cracking, but this will leave you with a bright silvery bead that will stick out like a sore thumb even if ground flush. For me, my go to rod for cast repairs is ESAB OK92.18 in 2.5mm. This is a true cast rod, and blends with the parent metal almost seamlessly. I have had great success with it on cylinder heads, engine blocks, hydraulic pump casings and many other things. It's big issue is the weld pool, I can only describe it as "fluffy", you will struggle to see the weld metal through the slag and you just have to be confident, A big tip to make the job easier and neater is the use sacrificial plates at both ends of the weld so the weld pool is well established as you reach the repair area.

    Chinese inverter welder

    Neighbour of mine showed up on the doorstep backalong proudly carrying an ALDI bought Parkside 130amp inverter stick and asked for some lessons, I'll admit to a little snobbery when he unboxed it, at £70 with leads, auto darkening helmet, chipping hammer and a small pack of rods how good could it be. Well for a start it comes with a 3 year money back or like for like guarantee. No need to post off and register like some of the trade names just rock up to your local store with the receipt, so in theory you can't loose. We ran all the 2.5mm 6013 rods it came with pretty much non stop, partly as he was keen to learn but mostly to see how long before it overheated or popped. It ran fine so we moved up to some 3.2mm 7018 that I had in the van. He didn't like them but the welder never even faltered. For that £70 you could nearly call it a disposable welder on a site job and for DIY around the house I don't think you could go wrong.

    New to welding, Advice please!

    Thank you very much Ditchman. I take that as a real compliment from yourself. Very little chipping mostly just wire brushing, by the time you've completed the other side of the run the first one has cooled and the glassy flux shatters. Unless..... you have the amperage too high, in which case the flux runs into the undercut and glazes over the bead like a diamond coating requiring a needle gun, a hammer to rival Thors and 4.5 inch wire wheel mounted to a 9 inch grinder to remove. A mistake you only make once. Trust me.

    They can be hard to restrike part way through a rod as when you stop the slag seals the end of the rod, either a little whip at the end of a run to flick the slag off the end or a tap on the end of the rod with the side of your chipping hammer will make a big difference. A little trick I use when running 5mm rods is a piece of an old file tacked and screwed to the handle of my chipping hammer to quickly dress the end of the rod for restart.

    I think that was me and it was 7016 rods. I'm sorry you didn't have any luck with them. They do need an open circuit voltage of 60v and above to burn, some of the smaller inverter units run at around 48v and will struggle or just plain refuse to run these rods.

    Digital safe repair

    We use these safes at work for vehicle keys and find the drivers slam the doors so hard the batteries launch out the rear of the battery box. Solution, cheap battery holder off fleabay and a short length of twin core speaker wire. Double sided tape it to the roof of the safe extend the wiring off the board to the new power supply. Job done. Word of warning though, these safes are the frighteningly easy to break into. And offer nothing more than the slightest of deterrents to a would be thief.

    Holiday reading

    Somme mud by EPF LYNCH. Aussie infantrymans diary of the first world war. Gripping funny harrowing but unputdownable. First light by Geoffrey Wellum. Youngest spitfire pilot to fight in the battle of Britain. Past away only last week at 96. One the best accounts of both dogfights and ground life during early ww2. Both relatively short books but will stay with you for a long time after.

    Charts wanted for arc welding please

    They are a bit specialist but give a beautiful weld with virtually no manipulation needed to manage flux. 6013 will do the job yes but if you want a pretty set of railings then splash out in the 7016. If you can' find them locally let me know. I'm sure I can sort something out.

    For 3mm wall tube onto 6mm plate I'd go with Oerlikon E7016 in 2.5mm. 75-80 amps. This is our preferred rod for 90% of our jobs at work. It's really forgiving The flux is like molten glass and you have to be doing something really wrong to get any inclusions.

    Bought some ‘art’

    Trudging around behind the missus shopping in Lynmouth the other day this stopped me in my tracks. The original in oil was outside of the artists studio and at 3ft by 4ft is so striking it genuinely moved me, I just couldn't look away. Couldn't afford the original so looked at buying a smaller print but it didn't seem to have the same impact. Wandered around the gallery admiring other pieces and trying to justify to myself that when something touches you like this then it's worth the price but walked out as we just don't have the money to spend. As we left we passed it again and the impact was just as strong. A strange experience.

    Hodophobia

    This. 4 years ago I left the house early to go to work in a bad mood with the missus. Didn't stop to kiss her or my little girl goodbye. Three hours later I was involved in an accident that should've killed me. When they rushed me through A+E to surgery I clung to the theatre door frame with everything I had left until they let my wife though to see me. It hasn't affected me so much but my wife hates me working away now.
