Lol....my 90 was the first saw I ever had with decomp....never use it. After pullin' on Husky 2100's most of my life, it just never occurs to me to use it. The Jonny's though, seem more likely to take my arm if I'm not paying attention. :rolleyes:

Probably the difference between a hot CD ignition & a old points set-up, I suspect.

Yep an alum plug with a hex hole on the bottom more or less in line with the crankshaft center line .....don't need to remove the plug to adjust.... just get the right sized flat blade screwdriver to fit through the hex and turn the adjustment screw within...screw in = less oil...out = more oil...

I think you need to loosen the plug to adjust...if the plug is tight against the oiler.

I will try to find out tonight.
Many thanks.
 
You only need to remove the plug to pull the oiler assembly out. But it seem like I remember that if the plug is screwed tight, you can't adjust the olier through it.....might be wrong though. In any event, stick a small flat-heat through the plug and try to turn the oiler screw head. If that doesn't work then loosen the plug. As Robin said; IN to reduce oil flow, OUT to increase. There's a point though, that when turning OUT is excessive and you've gone too far.

I'll try it at lunch. Got it warming on my bench.
Thanks.
 
can anyone help me with the true application of this bow bar? the oiler and adjuster holes line up with the current saw it is on (520)SP which looks to be carrying .325 chain. The saw has been modified greatly to accept the bow.

i want to put the bow on the intended saw.

thank you 100_3476.JPG
 
Well...My fellow Jonsergeeks.....picked this up off ebay last night......nice clean unit.....nice paint and plastic.....however the wrap handle has a "custom bend"...LOL!! What piqued my interest was the top mounted decomp....another "custom" improvement...I don't think they ever came with a factory decomp....anyone ever see one?? Add says it turns over very hard.....probably scored beyond....maybe crank bearings....or both who knows. I'm pretty sure I have everything in stock to make into whatever iteration I want it to be.....even stock... so no worries there. Just very hard to find any of this family in this good shape. Of course time will tell if I made a big mistake or a decent deal.

Lol...I admire you skepticism. Like mine, it's well-earned from past adventures in buying. It's not old enough for me, so I can't contribute to what it has versus what it should have. Yeah on the 'turns over very hard' part....could be all the bad rather than good compression. But who knows...like unwrapping a Xmas package! Let us know what you really got when it arrives.:popcorn:

Decent price for ebay though....

Yeah....he didn't imply that it turned hard due to compression....turned hard because he thought it Might" need to be rebuilt.....I expect it does!!

Like you I was not interested in plastic on saws.....and said so numerous times when my first 630 Super II came my way.......but I've since become quite fond of this family of saws...Jonsered and Husky........the weight and performance is quite intoxicating....I have never wanted to pick up a 625 simply because it is almost completely the same as the 61 Husky.....the lowest output saws in both families......and I have the regular 61 in my sig that I bought from a client when the original chain was 50%.....that's been a good saw for the last 21 yrs...still is......was my only running saw until I stumbled onto AS......now look at me!! 52 running/rebuilt RED saws under the bench.....LOL!!!
 
Man....you got it bad, for sure!:p I'm at a point & age where collecting stuff has to have its limits. My youngest son says I'm a 'horder'. To me a 'horder' is somebody with paths through the junk in their house or garage...I'm a long way from that. If I collect something, I think three is ideal...so three 80's, three 90's and three Husky 2100's....and then I'm done. :rolleyes: Well, maybe.....:confused:
