Husky 42 Special advice required

[ally]

Hi , I`ve got a 42 special that sat in my shed all winter unused after I was involved in a car accident . It starts easily but won`t run for more than a few seconds . I`ve had it for about 8 years from new and it`s been a good little saw except for a couple of times when I was giving it too rich a mixture .

 

I`m not mechanically minded but my father-in-law who is reckons I need a new carburettor . Does this sound right and anyone know where I can buy the right parts online for it ? .

 

Cheers

Was it stored with fuel in it?

When you got it out again, did you put fresh fuel in it?

[spudulike]

The fuel tank needs clearing of old fuel, put new mix in it.

 

As for changing the carb...Nah, let the new fuel come through, try revving it lightly and seee if it will settle. If it revs up Ok then increase the idle a little but make sure the chain doesn't spin once a good steady idle has been achieved.

 

The carb may need a clean but not a new one!

It was empty when I got it out of the shed but I hadn`t run it `til it stopped out of fuel as I know you`re supposed to if putting it away for a while .

 

It starts easily from cold and runs for about 7 or 8 seconds and will rev up but then just dies away . Starting it immediately after that it will only run for 2 or 3 seconds before cutting out and will not start so easily after that until cold again .

 

The F-I-L took it to his friend who is good with saws but he couldn`t get anywhere with it either , hence they reckon it`s a new carb .

 

I`ll have another play around with it and adjust the idle if it will go long enough ! .

 

Cheers for the replies .

Ah, that sounds like a blocked breather, try the saw again and as soon as it is running, tilt the saw so it is almost on its side and loosen the fuel cap, my thinking is it will run fine.

 

If it does, the fuel tank vent pushes in from near where the fuel line goes in to the tank, you will probably have to push it out from inside the tank by pushing on the long grey tube that runs along the top of the tank or cleaning the outside of the breather by undoing the AV connections and getting a bit of a gap between the handle and engine cradle!

Where abouts are you. Could be someone close by that would know more as it sounds like you don't really trust the F.I.L or his mate.

 

If the breather works out ok could it be old jellyfied fuel in the carb that needs a blast out. Or a knackerd diaghram???

 

Just throwing suggestions out there.

I think you`ve nailed it , Spud ! I got it running for quite a while on its side and it was revving just as normal .I stopped it because there was quite a bit of fuel leaking from either the fuel pipe or between the fuel pipe and the grommet where it comes through the housing before joining the carburettor .

 

I emptied the tank but can`t see anything inside except the fuel pipe with the filter on the end , there doesn`t seem to be anything near where the fuel pipe exits , there is a thing like a thin black rod running crossways at the top of the tank but I`m guessing its a bolt.

 

Could you give me an idea of where this air vent might be from the outside and what it might look like ? I`m not sure what you mean by AV connections .I`ve taken off the air filter and the white coloured housing that slides over the adjustment screws and carries the blue and red wires but I think I need to get at where the fuel pipe leaves the tank area ? .

I`m in SW Scotland Rich . The nearest Husky dealer is quite a bit away and told me they couldn`t look at it for a couple of weeks ! . I can`t think it is the carb. now I`ve had it running well on its side , reckon it must be the blocked breather as Spud says .

Bingo:thumbup: He shoots, He scores:lol: the grey tube is a pipe, when the saw is on its side and running, it stops the fuel seeping out of the breather that is connected to the outside end of the pipe.

 

If you have a can of carb cleaner or WD40, you need to point the thin plastic pipe to around where this grey plastic tube exits which wil be near where the fuel pipe also exits.

 

Chances you have a lot of oily crud laying on the breather blocking it. Generally it will be a piece of permeable fibre or that sintered metal breather material.

 

The AV mounts are Anti Vibration mounts, they normally locate on to springs or rubbers eithar side of the tank and if you undo both, the fuel tank will drop a bit and enough to get a bit of solvent or cleaner to the breather to clean it.

 

Best option is to drive it out to give it a good clean but next best is to clean the surface of it!

 

Good luck

The man`s a genius , cheers Spud ! . Got the pipe out and cleaned and everything back together , now just making a few adjustments to stop the chain turning at idle but starting and running well . All my own fault as the saw was filthy and hadn`t been looked after properly , so lesson learned there as well .

 

Many , many thanks ! .
