I brought a chinese saw off ebay which I have run 3 tanks of fuel through and it has surprised me, its still going!
I was giving it a service yesterday and found the air filter had not been doing its job, lots of saw dust getting into the intake! I think this saw is a Stihl copy? Does anyone reckon I might be able to buy a Stihl air filter that will fit? Or at least a foam filter to fit?
I have the same saw, bit sad when you buy something and it comes with a bag of spare parts. (I got a spare starter reel, oiler and couple other small bits.
dunno about the air filter.
Mine still runs okay after 6 months or so, it would probably run better if it were used more often.
Hello Joe, I thought I saw a post from you a while ago saying you brought one. I did not get any spares with mine! Can you check the air filter and intake on yours to see it it has been sucking saw dust etc through the filter?
What I am asking is if anyone would know if a stihl air filter looks the same etc so I can buy a stihl one to use and will fit straight away?
Hi, I've just bought a stihl chinese copy from "trade tools direct" and purchased a spare filter for about $7. There might be one of their shops in your area.The filter seems to be well made. Hopefully this is helpful. Ken
I ended up throwing the filter out, wasnt really keeping much out, and kept getting in my way while mucking about with the tuning. Yet to buy a decent saw lol....
I ended up making a foam insert to put inside the original air filter. I cut some foam and put some foam filter oil through it and its good as gold now.
Joe my saw have been flogged and I have never touched the tuning and goes well. I have worn the chain and the bar out already.
We've bought two of these machines over the past year... a 52 and a 62CC model. The 52 has worked hard with no problems at all. The 62 stopped running recently.
It runs a HUAYONG carby - pulse driven from the crankcase. It turns out that the genuine pulse tube - (5mm)showed some signs of damage and the carby membrane gaskets had failed, stopping fuel being siphoned up from the tank. The 5mm tube came from a Kawasaki dealer (oil line) and the gaskets were pulled out of an old Ryobi whipper snipper, the parts internally being identical. I'll find a new replacement set of these prior to full assembly - but the unit is running again - and well. Oh - and the tuning is similar to the Stihl... wind the H and L screws ring in and then back them out 1.5 turns. The L setting was further adjusted by about half a turn with the engine at full revs.
Thought I might share this info here for the next person who strikes these problems!
That sounds as if the carburetor was badly designed, so there is still vacuum at the idle discharge ports when the throttle is fairly well open. When you tune the L screw for best high speed performance, does the engine still idle properly?
Mine finally died permanently on wednesday morning. I left it out in the sun for no more than a couple of hours while I carted away a ute and trailorload of wood, upon getting ready to cut my next load I went to pull start it and the starter casing had gone soft enough to pull out of shape. In the bin this one goes.
With the carb adjustment, I found the same also, it also required constant adjustment to run satisfactorily.
Well, my Chinga saw has decided to start needing a carby tune every time I use it like others have mentioned. I was cutting tress, rocks and dirt with it at the time, during the Xmas break. It is still going though, so i may need to pull the carby out and have a look.
I am surprised it is still going, as i have cained it for the last 10months or so.
I have replaced the needle and the diaphram in the carby and flogged the saw a again this weekend. I had to retune the fuel mixture only once during the weekend so I think I have it running ok again. I did find over the weekend that I have worn another bar out, so thats 2 bars and 2.5 chains and 1 sprocket so far.
MVC, it sounds as if you may be using the wrong bar oil, or the oil pump isn't working properly. Engine oil will not work to lubricate the bar - you need bar oil, which has an additive that makes the oil very sticky. I've bought it a couple of times at my local flea market - $16 for 4 litres. Great stuff - I use it as way oil on the lathe and milling machine, and anywhere I need oil to stay in place for a long time.
Chainsaw oil pumps are often poorly engineered. Also, if they have ever had dirty oil put in the bar oil reservoir, they are destroyed immediately. If they don't prime properly and pump reliably the bar wears out very quickly. The traditional way to test that the oil pump is working is to hold the saw with the bar end on, a foot away from a fairly light-coloured vertical surface, and rev up the saw. Expect to see a vertical line of oil appear on the vertical surface immediately. If not, shut down the saw and start dismantling the pump - again.
Yeah I have been doing a lot of work through. I do hear you on the chain oil. I always check to make sure the pump is working fine. My property has a very sandy soil so I think that it could be the main reason, I do try to clean the bar and chain every week to get rid of all the sand etc.
I may run correct chain oil in my Stihl to see how it goes.
