Looking for ring size for my ea6100 ?
I wanna put a new caber ring in it and not sure but I think it's 1.2 mm

Thanks
Ernie

315-132-020 Looks like same ring as 6400. 47x1.2mm

Looks like a Dolmar with a Bavarian twist. A buddy of mine picked this up recently. The tag under the clutch cover is blank with the numbers 93 309 stamped on it.View attachment 464299View attachment 464300View attachment 464301

I'm totally going to have some Wacker t shirts made with the jackhammer man logo. You know, 'cause they made good cutoff saws...

Same on PS-6100 & PS-6400

Current part number:

I finished reviewing my recently acquired DOLMAR 152.
Piston was severely dented so I had to replace it with a new GOLF piston.

Few more gaskets, carb diaphragms, a bit of cleaning and there she is:



Unfortunately the ignition (a Bosch KDT-type electronic ignition) doesn't work and gives no sparks.
After measuring the transformer and seeing reasonable resistance values, I tried the fix Jim described

Here ya go with some pics and here’s a link for the capacitors.

Soften the potting with a heat gun, hair drier and then you can pick it out with a pocket screwdriver. Clean down to the circuit board here.
Now, cut the trace and remove about 1/8” of it. This removes the faulty cap from the circuit.

Now solder a wire to that long trace, make it long enough to reach...

• 

but with no success. Still the ignition doesn't fire.
Seems like a have to look for a replacement ignition...

 

[FATBOY2017]

I have one of these that I want to try to see if it can be adapted to fit Dolmar's. Not had chance yet!

Pardon our interruption...

I tried that one time plate is bigger than dolmar. Tried swapping just the trigger. Couldn't get any of it to work with the dolmar flywheel

As a last ditch effort could use point conversion transistor chip. Then either slot the holes a lot or use point flywheel. Here is one I did that the capacitor didn't fix

 

[old_sir_henry]

I see conversion to ignition chip could be some kind of last resort but would like to avoid such both-up (no pun intended).

I currently have been offered a used 152-ignition which I will give a try first and if that doesn't do the job then
maybe switch to pointed ignition (I have NOS in stock, only will need a pointed flywheel since mine is missing the cam)
or I might try a 119/120 ignition (hoping they are easier to find than 152 parts).

Any 119 or 120 ignition should work too. Just make a mental note of where the flywheel key is early 119 was different than 120 and 123. Key was in the same place as points but didn't have the cam

 

[old_sir_henry]

A german collector sent me a used ignition harvested from another DOLMAR 152.
It has the same Bosch-number than the faulty one built into my saw.



Built in the "new" one today and it gives me strong sparks!
Tried to start the saw and BINGO — starts and runs fine

 

[old_sir_henry]

Now that my 152 is running, I carried my other members of the DOLMAR 114 family of saws into the garden to join for some family-snapshots:





Bottom pic, front to back:

SACHS-DOLMAR 153 (the 144 line's final development step)
POULAN 6000 (a DOLMAR 152 in disguise)
DOLMAR 152 (my recent acquaintance, a very early specimen and except displacement very similar to...)
DOLMAR 144 A (2 of them, the revised and improved 2nd version of DOLMAR 144)

What's still missing in my collection: Early 144 and late 152.
For now I'm very happy with this bunch of beauties, all of the are runners and some have been shown at GTGs.

 

[old_sir_henry]

Another one missing in my 144 family:
Poulan 5500 which is a Dolmar 144 in green clothes.

 

[FergusonTO35]

I've never even heard of the 5500 so they must be quite rare.

Looks like it was only made one year. Lime green really pops on that model!

[Jrmy_1]

Yup, I bought one out of Europe recently to add to my spare parts stash

Where do you buy them from in Europe? Looking for one to put on my 6421 and everything I'm finding is $200 ish.

I'm having a heck of a time getting my 5100s running... It fires on choke, and on run (high idle) the saw starts and immediately dies. This makes me reckon it's fuel, or an air leak. So I rebuilt the carb, and tested it on my other 5100, where it was running fine. Then I do a pressure test which it seems to have passed, and the saw still does the same thing. I even made sure to turn the crank while pressure testing, to see if there was a leak while rotating.

If anyone has any ideas, I'm all ears.

Did you pressure test the fuel line and vacuum test the fuel tank while the carburetor was off ? It the tank holds vacuum the vent is bad. Sometimes fuel line develop hair line cracks.
