Lately, my chainsaw has been difficult to start. I have to pull the starter about 15-20 times before it fires. Time to take it apart and find the problem. Might be a dirty air filter or clogged fuel filter.

if it doesn't want to start, or it finally starts and it is too weak, not cutting at all, then the problem can be that the chainsaw "can't breathe". i have a fairly similar chainsaw but with a different brand, and all i had to do was to unscrew the side where the smoke comes out, inside there is a small metallic panel with tiny holes, "sorry for bad english" this "metallic panel with tiny holes" was really dirty, greasy, burned oil on it, and it didn't let the smoke come out. now after cleaning it with a bit of gas and a steel brush, assembled all back, the chainsaw started. good luck.

Great tip thank you Mihai, the name of the metal plate with holes is a "spark arrestor"

@@davekennedy52 I have some updates! It was quite tricky but at the end I solved the problem, completely. Carburetor was the main problem, i cleaned, i changed membranes, I tryed also to change it with a new one carburetor but after a couples of days the problem come back. Solution: clean the muffler! Defective carburetor means also unburnt leavings and little by little they completely block the exhaust

There was no need to disassemble the carburetor. It was enough to clean the air filter and everything would work!!! No equipment can work with such a dirty filter.

Thanks Guntar, you're right, it was really dirty, and as you could see the fuel filter was pretty clear as well, but at least the whole saw got a good clean and I do that regularly now

Hi Dave, and thanks for the video. I've borrowed this from a neighbour and want to put a new chain as his is blunt, and it's the least I can do. That chain cover at the beginning 0:51 - it has a round clip that must go over the cog mechanism - but mine just sits tight on the edge. I can't seem to get it to "pop" over the housing at 9:25, and there's no obvious adjustment. Can you help? I don't want to just tighten it.
@davekennedy524 жыл бұрын
Hi David, I think I understand your problem. At 0:51, the round clip/ring is the brake and it should fit over the "cog mechanism" which is the clutch. The brake is activated by the big plastic hand guard at the front of the machine. You can see it at 0:58. at the moment your brake is on and the ring is activated and smaller than the clutch. Quite easy to deactivate it, you just have to see how and where it connects with the hand guard. If you still have a problem tomorrow, I'll take my cover off and see how its connected

Both ebay and Amazon have the cords. I've also never seen them in a shop, but then I've never looked for them:) Never had one break before but once I tried to burn the frayed edge and it didn't melt so its not nylon or polyester. Maybe its a cotton rope?

Hi Daniel, remove the cover (4 screws) then take out the yellow plastic dust cover. Remove the small screw and washer on the plastic spool. Thread the new rope in from the side of the spool and up through the hole. The rope loops around the screw then under itself again. At this cross over point you could get a soldering iron and melt the nylon rope to make it secure. Then replace screw and washer to hold in place.Very important that your new rope is long enough. When starting never pull the rope all the way out until the end because your spring will definitely break. I've done that. So measure your old rope first. If you're thrown it away I have the measurement for you. Watch this guy for tips on initial threading and also winding rope on spool. If you need more help just shout. kzbin.info/www/bejne/eJ2lp3mjf7l3kNE

Hi, I've been searching for hours for a video for a Mcculloch CS 380 video/service, this video is as near as it comes, What make is this?) You should change the title to help with seaches including the name Mcculloch. My chainsaw wasn't starting up/ staying started. I let a "friend" have a look at it who said he knew what was wrong with it. He said a small piece of plastic fell out of it when he opened it, ( carb area) For the life of me I can't tell where this plastic goes, he seemed to think it was something to do with the choke, but after looking at the chain saw, and your video there is nothing I can see where it would go. so the video help. Ta :)

Hi Andi, you're spot on, its a McCulloch CS340. I'm really starting to like the brand, also have 2 McCulloch lawnmowers. And thats the worst when small plastic items or springs pop out of nowhere. Hope you get your chainsaw back in one piece. Also going to change the title at your suggestion-thanks")

@@davekennedy52 Hi, thanks for your reply. I'm not a big DIY, er so been searching for help on U tube. I have a Mcculloch CS 380 they must be very similar to the 340. I have worked out the plastics not off this product. Hurray. I have been having Starting problems with it starting then stopping after a few seconds. I have now noticed that when I take the fuel cap off I can hear a sucking noise as it sucks in air. But the cap doesn't seem to have a breather hole. However, Where the fuel line enters the fuel tank from the primer, (behind the carb) I can see a small round hole next to it which looks like a breather hole, it Looks like a round brass coloured filter. (does yours have one too?) Is this the breather hole that usually on the fuel cap? Can it become blocked and how would I clean it? I also noticed that when I purge the pump there is air bubbles in the two fuel lines from the primer. ( but not in the fuel line from the fuel tank to the carb) I have photos but can't send them on here. Any ideas of the problem? When I took off the carb I can see The fuel lines look ok. Although I have managed to change two, I can't seem to reach the 3rd fuel line that goes back to the fuel tank from the primer. Feeling bit frustrated as I know this problem is solvable without going to a repair man , and paying big bucks. PS; we live in France. Ta . You should do more detailed videos for this product, as I'm sure theres a market for it. LOL

@@Andi1xx Sorry, I've been awa y for 2 weeks, solved your problem yet? Not too sure if I have the filter on my fuel tank. Pretty sure your problem will be in your carb. If you take off the cover of the carb on the inlet side you'll find a little circular filter. Take it out with a needle or pin and clean it as when its blocked not enough fuel gets past causing cutting out and idle issues.
