Anyone know owt about chainsaws?

[breezer]

My dad's got a Partner 351 chainsaw which he's had for a fair few years.

All of a sudden it started playing up, we cleaned the carb & changed the gaskets, tried a new plug etc but still the same problem.

Shortly afterwards I discovered my new chainsaw exhibited exactly the same symptoms when it was running out of petrol, so I suspect it may be a blocked fuel filter.

the only thing is I can't find it! Anyone know how you get access to it?

Cheers

Jim

It could be on the end of the fuel pickup pipe in the tank, similar to strimmers.

 

[oilcooled :)]

like wyn said it should be in the tank, you need to fish it out through the fuel cap to clean it

 

[breezer]

Cheers chaps will give that a go.

Don't know why I end up doing all his ****ty jobs!

changed the fuel filter still no joy.

Will run for a bit after being started with the choke on, then it just dies.

Plug is a bit black, not sure if that is down to it only running on choke.

Not changed any settings.

Bloody thing

sounds like the two screws on carbuerettor need to be wound in and reset to adjust the fuel air mix. all the old homelites had the settings in the manual not too sure about newer saws tho?

The exhaust and exhaust port area can get clogged up with carbon. It might be worth taking the exhaust off to check whether it's clear or not.

Are you using old petrol? petrol loses its octane level

try not to keep it in a can any longer than three months.

 

[breezer]

Checked exhaust, checked settings, fresh petrol, nothing doing...

no idea what is wrong with it! It's got me stumped.

Cheers for the ideas though fellas!

It's just coming to that time of year.
I can remember my fathers battles with his shagged out mower every spring, did we laugh? maybe.
I have a mate who is the 'youngster' at an engineering company, anytime now a line of mowers starts to appear outside, and gets longer and longer.

''it was ok last year when I put it in the shed'' How he hates them, the people and their poxy mowers.

Sounds like the carb has varnish on the mix needles.

Is the mixture not adjustable?

Could be pump diaphragm/check valves ware not sealing well.

 

[breezer]

no needles - it's one of those carbs with a diaphragm rather than needles.

 

[Justme]

Sounds like a blocked jet.

 

[shenion]

Heard a new tip on cleaning jets. Sometimes they get tarnished and varnish. Boil them in 50/50 mix of lemon juice and water and they will clean right out.

I also keep a #60-80 drill set for cleaning them. Just push bit through backwards.

sounds like setting screws need resetting


take it to a service center... local hire shop, about £30-40 & sorted


much less grief & less likely to end up through a workshop window LOL

i had a stihl chansaw which went the same way turned out to be the piston rings it even felt as though it had compression tried everything like you have £8 on a set of rings and good as new

 

[breezer]

Hmmmm... piston rings...? Interesting idea. Might try a bit of neat 2 stroke down the cylinder to see if it runs a bit longer like that - it's a good way to tell if the rings have gone.

I've blown the jets through with a compressor and I'm sure they're all clean. I like the lemon juice idea. I also picked up a bargain ultrasonc cleaner from Tchibo - £6.22 as they were closing down. It makes a good job of carbs but you do have to run it a few times.

To be fair to the saw my old man is confident he's had his money's worth out of - he had a McCulloch saw he'd had ever since I was a wee nipper (which must have been 20+ years!) and took it in for a repair, the shop couldn't get the parts and so offered to replace the whole saw with the Partner for the cost of the repair (£60 I think) He's had that 7 or 8 years and it's had some hammer.

With that in mind he's not mad keen on spending a £30-£40 on a repair. He's also got another couple which he bought a couple of years ago when he thought there were going to be regulations introduced which meant you would need a chainsaw ticket to buy one. Never happened, but he'd stockpiled just in case!

my rings were stuck in with carbon but broke getting them out (was rushing) so if it is the case you could soak the piston to loosen them

Every few months I get this idea to sort my poulan countervibe out, drag it out the corner, prod it with the pointy stick, pour petrol down the plug hole and pull the cord for ages until it makes a single solitary sick bark, then decide I need to take the engine apart and see whats up inside as the compression feels low, but then havent got time. Try it a bit more, throw it out the door into the courtyard in disgust then a few hours or days later go pick it up from where it landed after my wife naggs me about discarded rubbish and put it back in storage muttering to buy a piston kit or rings. Then in a few months of course I haven't got organized and bought the rings, but I still repeat the above when I need a saw like Im suddenly going to find out why and have the parts on hand that day.

Your dads probably a much wiser man than I am wanting to just use a new saw
