chainsaw repair help wanted
hi i have a homelight 46 cc chainsaw yes its a cheapie
i dont normally mess with these tiny motors but thought i have another go and have ended up frustrated as usual.

my question is about the carbs on these things. it is a carb
problem initially it would not start and run no matter what
without ether own the throat so i disasemble an cleane the carb because there was a very good chance of old fuel and
other contaminants.

now i can get it to run with 3/4 choke but it shuts down
when the choke is removed.

i think i got the jets cleaned but could not work out how to
remove from the carb body is there some rubber gasket pump?
that could be causing this

and is this just a throw away job?

Not sure, OP, but if it runs 3/4 choke and dies full it's drowning in air.

Re: chainsaw repair help wanted
Hi if the jets in the carb are blocked a quick fix is to remove the air filter start the saw then block the air inlet this will force fuel through the carb and clean it out. Another trick is to spray WD40 into the air inlet then start the saw. I got so pissed off with little 2 stroke engines I bought a gen with a 250cc single 4 stroke engine and electric tools.

Re: chainsaw repair help wanted
You might be able to get a new or rebuilt carb for it really cheap, I'd try that.

Otherwise, it sounds like the primary jet is still a little clogged. Did you soak everything in carb cleaner for several hours?

And yes I'd consider that product a throw-away. Hell my parents almost buy a new lawn mower every year because they don't take care of anything.

Good luck OP, sure is a good feeling reviving an old motor, but frustrating when you fall short of purring like a homelite kitten!

Screw air and fuel jets in until bottomed(gently) and then screw out 1/2 to 3/4 turns and then fine tune.

Oh so you have a generator and use an electric weed wacker? Never thought of that but I don't like extension cords when I'm doing that stuff.

Re: chainsaw repair help wanted
Try adding about 8 or 9 eyedropper drops of acetone to your saw's fuel tank, less if it isn't full. Presumably you have the correct mixture?

The acetone will get the saw running. See how it performs with fresh mix.

Check the gas line...it's probably cracked somewhere. You have to change it every couple years anyway.

You really should be cutting wood in early spring btw.

Re: chainsaw repair help wanted
Yep same mixture i have always used and i dumped out the old fuel and replaced it with new.

Im thinking as well it might be a good idea to go with all
electric chainsaws like another poster suggested in the future. Im off grid and have all the electricty i need to run a saw anyway and i have been replacing my small saws every year just about anyway.

Check your gas line. Also the gas filter in the tank.
Check your plug for gap and fouling.

This is correct 99.9% of the time the hose in the tanks crack and draws air instead of fuel.

Re: chainsaw repair help wanted
I switched to an electric (corded) lawnmower, weed trimmer, and blower. Next is the chainsaw.

I highly recommend electric, but you're limited to about 125' of cord. It's not hard to avoid wrecking your (expensive) extension cords if you pay attention.

It's nice to let it lie dormant for 6 months and know that it will still start right up.

I have a generator to use if power is out, or for more mobile applications.

Homelite makes decent products for how cheap they are. Ryobi too.

Yeah pretty much. Wood needs a good 6-9 months to season.

Re: chainsaw repair help wanted
Its probably the pick-up filter. The acetone is a good idea but dont use more then a few drops like the guy said.

I know you know this but those saws are trash.

I run four Stihl saws, a 066 mag, two 036's and 028 super, sometimes pretty hard for months on end. These things are bullet-proof, and easy to fix. My first 036 is going on ten years old, and I have been through more then a few bars/sprockets, this saw cuts like a mother-fucker, and only seems to get better with age.

Even a used stihl will serve you better then a homelite. Do a little research and buy one on ebay. The 036's are almost as powerful as the 066 and don't weigh nearly as much. Amazing saws.

When it comes to things like chainsaws and any other serious power tools, where you might really die if something goes wrong, I highly recommend getting the best gear you can. Operating chainsaws is a pretty big risk anyway, and it sucks when you get to the job and the saw quits.

Make sure to get mostly maple & oak. Also 1-2 cedar make good kindling.

I have a little poulon, but as long as you keep the chain sharpened it doesn't really seem to matter.

I have burned hundreds of cord worth of green/wet wood. The trick is to stack the wood around your stove so the heat will dry it out. Helps bring up the indoor humidity a bit too.

Of course it is best to let it dry and season, but its not entirely necessary.

Depends on how much room you have too. I've just had better luck seasoning it. To each their own :)

Ive burned my share of green wood as well using the same trick even sometimes when i have a good supply of well seasoned i will throw in a bit of green to make the fire
cooler and slower burning.

But i do know much of the energy stored in green wood
will be wasted to dry it out so its not my first choice
normally.

OP here btw i got such good advice here today i signed up
the saw is running again just finished cutting some wood

it was not the lines or filter this time i knew about that
and it was one of the first things i checked.

i guess i messed with mixture when i cleaned the carb.

sheell be right mate
