Sachs Dolmar 111 Pull Start Slipping & Choke Question

[NoPaint]

Gents,

You guys helped me get the last Dolmar running like a beast so hopefully you can give me a hand on my newest addition to the collection. I have a Makita 520i that I've been running for at least 15 years. So I just got a Dolmar 111. Couple issues:

How does the choke work with the top cover attached. The choke is slotted into the case so I can't pull it back...how dumb am I!? Attached is a picture of the choke with the top cover off. As I see it, the choke pull is slotted into the case and I have to lift the lever to choke it. But I can't lift the lever to choke it if the top cover is installed.

Second: the pull starter slips...the actual pulling mechanism runs smooth. Could it be the two spring loaded things on flywheel? Not sure where to start and I don't like just throwing parts at these older saws.

I just checked for spark and it has that so once you guys let me know how to keep the pull starter from slipping (I can get some cranks but not a good smooth pull) I am going to try to start it and/or rebuild carb.

I may be way out of line I don't know the saw But could the choke
lever assy be upside down . slide it out of case rotate 180 deg.and
reinstall . then lever would pull down from top cover not up toward it .
Or is it just a slider pull out on, push in off ??

 

[NoPaint]

Sorry I wasn't very good at explaining. The choke slider is a pull out and push in. But its slotted and so I can't pull it out or push it in. There has to be something obvious I am missing.

But I can probably getting it running sans choke...the slipping pull start I really need to resolve. What could that be? I know used parts are out there for these but I just don't know what the problem piece is.

That choke lever looks to me like it should just pull straight up to clear the case of the saw and then it can be disconnected from the carb if you want.

 

[NoPaint]

Well I am not trying to disconnect it I am wondering how to use it under normal starting. How do I pull it out if it slides into the case?

 

[Mag Craft]

My suggestion is to take it out so you can see how it works. Also if I remember correctly there was a clip attached to the choke to limit the travel. I may have to take mine apart to confirm that.
I have a 112 and a 119 also and it may have been on one of those.

You know it may just need a good cleaning so take the choke lever out and see if the carb butterfly even moves.

 

[Mag Craft]

Also is it a 111 or a 111i ? There is a difference on the carbs.

 

[NoPaint]

Good idea on the cleaning. The actual butterfly moves fine but Im gonna clean the mechanism real well and see what happens. Not sure if 111 or 111i. Will look again.

Now the slipping starter. Is that usually in the mechanism side or the little sping loaded things on the flywheel. Both pieces seem fine but I can't see how the spring loaded things could be bad so I am assuming there's an issue with the pull start mechanism side? The saw is a 1987 so maybe there are updated parts?

 

[Mag Craft]

Spray a little WD 40 on the springs on the fly wheel and make sure that they snap back really fast.
Also inspect the plastic pulley that your rope raps around and make sure nothing is broken.
While you have the starter cover off pull the rope and look at the pulley. You can also use some compressed air and blow it out real good.

 

[NoPaint]

The springs snap back really well. I can't see how they could slip so I'm thinkin the issue is in the pulley side too. It can all be disassembled to check for damage or whatever is slipping?

 

[Mag Craft]

Yes it can be taken apart but, if you decide to take the pulley off do it carefully because the recoil spring can some times stay attached and you do not want to pull that spring out.

 

[NoPaint]

Ok just an update. The choke lever was just really stiff in the plastic housing so a little kroil fixed that up.

Took apart the pull start and reassembled: it has no problems.

The slipping must be in the spring loaded ears on the flywheel. How exactly can those be checked/adjusted?

 

[Mag Craft]

Those spring loaded ears on the flywheel are what engage into the pulley when you pull the rope. Then when you release the rope they ratchet the opposite direction on the pulley. If they do not return all the way, then they will not engage the pulley the next time you pull on it. There is no adjustment and just need to be cleaned and put some of that kroil on them to make sure they have full movement.
