Jonsered Chainsaws

Soooooo...are saying the flywheel key was sheared from the get-go....or, it sheared from all the pulling? Just the carb settings horribly off then....? Wow....and don't you dare post anymore small Homey pics, Dean!!

Kevin

Yeah...not sure about the key......flywheel was loose...key my have been partially sheared setting the timing off a bit or may simply have sheared when she fired because the wheel was loose......dunno...it looked like the break was not completely new...very finicky on the carb settings......like I said..I will probably run it through the USC and make sure everything is adjusted properly etc. Have to try a cold start later today and see how it responds....

Carb settings, sonofa . . . . . . . . I was so close.
Made it to the end of the rebuild and **** the rug!!!! heh.

USC=Ultra sonic cleaner for carbs(?)...cool. I bet that gets into every nook & cranny. I've just always used the sauce for a few hrs. What kinda solution mix do you use?

Is there any saw out there that shares the crank with the Jonsered 920/930?

820/830.

820/830.

Good to know, thanks. Got a 920 with a broken crank waiting in the wings for a rebuild.

You mean like Moonshine?

Yeah I bought one a yr or two back......bought a fairly good one...holds 6 ltrs with heat to 180 degrees F......works real well.....I've cleaned saw carbs in acetone and lacquer thinner...thought they were good....dropped them in the USC and in 5-10 mins. fine streams of dirt/crud can be coming seen coming out most every hole in the carb body.

Lol....no, although in the vintage analog hobby, my friends use Everclear to clean tape heads etc!

The "sauce" I use is the big dip cans sold as carb cleaner with a dip tray.

Would like to try this someday. Those things used to be really expensive and were used in the jewelry trade mostly. I've threatened to buy one for yrs for clock movements(another dumb, expensive hobby).

They have some really nice ones out there but they can be expensive. I just bought a small jewelry one with no heater. It's big enough to do a carb but that's about it.
I use hot water and some dish soap and then a couple of rinse cycles. It really gets them clean.

Oh yeah they do........make them big enough to put a whole big truck radiator in...descale a radiator really well. No "rodding" them out...no soldering..no nothing just back flush a couple times...good to go...Like I said mine holds 6 ltrs biggest bang for the buck I could find...about $500.00...but I am in business so the expense gets written off at the end of the yr...use it for many things other than saws....

Here's a couple pics of mine.....

 

[fossil]

That's beauty! It would be nice to have one that size for cylinders, flywheels and other large parts that are a pain to clean. I have to use soap and water and a brush but my arm doesn't get anywhere near to 40 KHz.

I went on ebay to browse the used models....wow! There seems no end to the styles & brands out there.....many don't have a heater or mention having one. I don't know how you can tell the snail oil, China cheapies from the good ones? I still think a motorized parts washer and the right solution is good for most things like jugs & flywheels. But for getting into small orifices like on a carb....I don't see how anything could work better than USC's.

I bought a used one that holds around 2 gallons for 200 bucks. It doesn't have a heater, but after 60 mins, the part will burn you from the heat it makes. Watch for the ones that are used for parts and avoid those brands.

Robin....I went to their website and even watched two videos;one specifically on cleaning carbs. I think I understand the sweep function in that it varies the cleaning frequencies for better dirt/grime removal. I understand degassing from analog equipment and to demagnetize tape heads, but in this appication the degas function is to remove gasses present in your cleaning solution(mostly from the tap water you use in the mix). I.e., it makes the cleaning solution more effective. At least that's the way I read it. It would seem your USC company makes a special carb cleaner mix....is that what you use?

This is a pretty good explanation and demonstration of how USC's work:

I didn't know they made a special carb cleaner mix......have to look into that. I used what they sent with the cleaner.......smelled like powdered laundry detergent....called it "general purpose". I've used "Cascade" and "Dawn" dish soap with good results or "Pink Stuff" which is a citrus base cleaner somewhat like "Purple Power". Most anything seems to work.....

I would imagine that heated Dawn would clean about anything on Earth. I finally got the Husky 2100 back together and running. Considering the jug is 34yrs old, the saw has cut mostly giants and I just used mastemind's "wigglesworth" mandrel/ScotchBrite method on the chrome plate....I got 150psi with new Cabers. Like everyone says, that should rise after a couple of tanks of gas. If I could get to 160psi, I would be happy. Sounds like a bear again, anyway. So now I'm off to the ebay 90 and why it has poor compression from a saw that looks like it doesn't have a lot of hrs. I want to start with plugging or replacing the decomp...it's toast. I see them all the time on ebay, but are those any good? Or do I just order one from a more modern Husky?

Being old school, I've never had a saw with a decomp except these 90's. I can't say that I like them...carrying the saw while idling and wearing cotton fallin' gloves, my knuckles hit the decomp and it makes a racket until it closes again. What joy for something I never use....

Was just fixing a Stihl 026pro for my dad. He straight gassed it by accident, so new jug, piston and ring. Since he's now into his 70's he commented how difficult it seems for him to start the saw. I pointed out the decomp valve and he said he'd never used it before . . . didn't know what it was for!!!
