SOLO Solo thread

[av8or3]

About 2 weeks ago, a guy from german chainsaw board wrote me there and asked for my
postal address, because he wanted to send me a packet. Since we have had forum conversations
during the last years I wasn't suspicious and sent him my address.
Last weekend his packet arrived: A +25 kg heavy weight when I had expected a tiny parcel ...

In it I found a complete saw including b&c

Solo Rex 125.

You suck, absolutely. What a gift!

Yesterday I have tried to run the Rex after having replaced fuel lines and diaphragms.

When given fuel into the funnel she runs for a few turns but is not yet willing
to keep running on her own.
Repeatedly pulling her 125 ccm really tired me, wish the saw would have a decomp valve

My Rex had no spark when I got it. So the first thing was to get that going. Wound up cleaning and adjusting the points, replacing the condenser and the high tension lead. Then I did the same fuel stuff as you. Only I used a repair kit that had new needle and seat, Welch plug , diaphragms. I also replace the o ring seals and washers that go under the H and L needles when I do one of these HL carbs.
Took a little adjusting afterwards but I’m happy with it. Runs and cuts good.

@av8or3:
Good tip with o-ring gaskets. I'll probably have to review the carb once more since I only
changed diaphragms.
If mounting and unmounting the carb weren't such a pain in the a**

Here is the new to me Solo 70 60122

Any idea what year?

 

[FederalQ]

Das ist so Geil! It sounds good too.

 

[av8or3]

You have a nice example of the Solo 70. Seems to run and cut good too! I have one but I don’t think it’s in as good as shape as yours.
I’d say late 50’s early 60’s. I don’t know of a data base where it could be researched by serial number.

[duwem]

Thanks Guys, anyone know how to tell the year from the serial number? Or at least a range of when the 60112 Solo 70's were made?

 

[FederalQ]

Interesting, “SOLO SMALL-MOTORS” was (is) located not far from Stihl’s headquarters. I know there are forum members from Europe on here that will hopefully chime in on the DOM.

 

[old_sir_henry]

Assume the year 1964 as the year your Solo 70 was built.
It seems to be a little difficult to be more precise: Most internet sources claim the Solo 70
being introduced 1964 but most of the same sources claim the 626, being the successor
of the 70 - early 626 even being designated Solo 70 Mk II - appeared 1963 which
is difficult to understand when the successor is older than its predecessor.

This one arrived today

 

[ajschainsaws]

Don’t know how restricted the muffler is

 

[av8or3]

Cool!

 

[old_sir_henry]

Interesting, even though not a Solo-by-ALKO but BKS instead.
This one currently isn't listet on ALKO's website (at least the german site)

 

[ajschainsaws]

Yes it isn’t listed on Alko U.K. neither it runs good after a tune up

it looks similar in design to the top handle that the mitox brand
Has on offer

 

[Graf]

it is listed on Alko.com/it, 3/8 lp or 1/4 pitch available, quite cheap Zenoah g2500t clone

 

[ajschainsaws]

it is listed on Alko.com/it, 3/8 lp or 1/4 pitch available, quite cheap Zenoah g2500t clone

Thanks for that I will have a look later there are three other models
Available over here in a conventional 40cc 50cc and a 61cc style

 

[ajschainsaws]

I’ve found it I think

[old_sir_henry]

For a Chinese clone saw quite expensive I'd think.
OTOH it shows the Chinese are catching up.

Just picked this old Rex up today, piston/cylinder look great and no cracked covers, also came with 2 spare right crank cases, spare starter and cover.
