Chid 6,376 Posted June 23, 2018 Report Share Posted June 23, 2018 Send it for a service should solve starting problems, if chains adjusted right and it’s still throwing it off the bars probably bent . 2 Quote Link to post Share on other sites

If they have a need to use a saw they should have their own. If they ain't got one they generally don't know how to treat a saw. I've seen everything with saws. Giving it back to you with plain petrol so you seize it up. To the chain is a bit dull ! They had only used it to cut through celcon building blocks !!! 》》》" it cut though them ok" duh ! To the young bloke that cut down a tree in his garden and it went out of the garden and blocked the road !! It's a wonder he didn't kill someone ! His saw bar was bent like a Z shape. The people who try to cut with the chain hanging on it like a washing line dragging along the ground. Its strange that you need a licence for a 410 but anyone can walk into b&q or wherever and walk out with a lethal tool like buying a chocolate bar.

Never again will i lend it out......along with the other problem it came back with a brand new chain completely blunt and bone dry in the fuel tank All this from supposedly cutting one 4" tree stump Quote Link to post Share on other sites
terryd 8,042 Posted June 23, 2018 Report Share Posted June 23, 2018 sharpen the chain and clean the air filter. Maybe change fuel filter too and see how you are Quote Link to post Share on other sites

His contribution? Zilch. Ex mate now. Cheers, D. 1 Quote Link to post Share on other sites
Caravan Monster 323 Posted June 23, 2018 Report Share Posted June 23, 2018 See if you can find a small engines man to have a look at it, I would be a bit worried that hard starting, hot running and high rpm could be an air leak which could be a pain to fix, but hopefully it's something more straightforward. I loaned a chainsaw to an old boy that I had found a month or so work for. He wasn't really physically up to the job but I felt sorry for him and did all the heavy work. He knew where I live and promised to bring it back. Never saw or heard from him again and when I phoned his mobile to get the chainsaw back, I got his former employer. It turned out he had stolen the mobile from them and had been using it long after he left, until they had the phone company deactivate it. Live and learn Quote Link to post Share on other sites
ollieollie 766 Posted June 23, 2018 Report Share Posted June 23, 2018 As said don’t lend stuff out, I learnt the hard way a few times Quote Link to post Share on other sites
tillylamp 1,809 Posted June 23, 2018 Report Share Posted June 23, 2018 hi bud, there should be high-low adjusters there along with tick over, get yourself a small electrical screw driver and wind the high and low clockwise to close them off, then wind each one back one and a quarter turns out, this should help with the starting problem, when it does start get it up to temperature then you can fine tune the high-low, what you do is....hold the throttle fully open with the screw driver in the high hole and turn it slightly until you get it running at it's best (you will hear it) then do the same on the low hole but from tick over this time, squeeze the throttle from low revs up to high revs and if you get a hesitant response just alter the low abit, then set the tickover to suit....then sharpen your chain and add the oil and away you go....and don't lend it out again.....hope this helps tilly 3 Quote Link to post Share on other sites
CHEVINFOX 3,537 Posted June 24, 2018 Report Share Posted June 24, 2018 tip the fuel out and but some proper mixed fuel in see if that works 2 Quote Link to post Share on other sites
Arry 18,580 Posted June 24, 2018 Report Share Posted June 24, 2018 I'm with Chevinfox on this one don't adjust anything till you empty the fuel tank new fresh right mix. Then start it warm it up, then with a lot of care if the chain is spinning adjust the tick over screw till the chain stops. Atb. Cheers Arry Quote Link to post Share on other sites

It starts spinning as soon as the brake is released There is a problem with the clutch. This could be down to the idle speed too high or a broken spring, or. The drum needle bearing has failed or there is so much crap in there that the drive is being transmitted. Check what fuel it has in the tank. Remove plug, ideàlly use pressure gauge to check compression to see if it has been seized. Or remove exhaust and shine light onto piston and wall to check for scoring 》》》 lack of oil sieze? Most carbs for a long time have not had mixture adjustment screws. The carbs are designed to work and thats it. A critical thing that most people dont realise is that fuel companies have added ethanol and this causes a gel like substance that block the very small accelerator jets. It is very important to use clean fresh fuel and a 2T oil with a D spec or low ash. Most people who use saws haven't got a clue about how to get the best use out of it. There are quite a lot of Injuries due to incorrect saw operation ect. Quote Link to post Share on other sites
