Today I got a sach dolmar 143 on a trade and it didn't have the brake handle on it but come with it. It doesn't look broke but just unhooked. I think im missing some parts for it to. I didn't take it apart yet but snapped a couple pics If someone could guide me to a assembly diagram id really appreciate it.
Or if you had pics of your own I could look at. Also can you tell me from my pics what im missing if there is no parts diagram available.
OK i will post pics later it says file to large and im not that great on computers lol

OK I got some photos on here let me know if I need any more pics. I see it has no band there must some sort of braking band?

It's worth the $$ they were asking. Ask chainsman1. I think he may have built a 143 more some kind of racing.
-
It had a brake at one time parts of which are still there but it was not a current style inertia brake.
Take inventory with the IPL?
-
Just Put a carb kit in it and a new plug. It runs like a new one now.
A new one with no chain brake lol

Looks like I just need the band. I printed off a parts diagram and I am going to check it out better tomorrow to see what I need for sure
-
anybody want to give me any secrets on how to mod this saw up a little? And what the little brass plug on the side of the carb when I put the carb kit in it I had it out and it has a little ball in it. I could pics if I had to lol
-
governor type thing. put a bb in them to defeat it from flooding the saw out if over the gov rpm range limit. ;)
-
so I should leave it alone? lol
-
Yes unless you want to remove it then it will rev limit your saw. If modding you want the passage blocked off.

Those 143 could be run a lot faster,but parts are very hard to find.the cylinder platings are not very durable.so every saw i found were scored.the one i own have been built a long time ago by somebody else.the fingers were too deep and the cylinder **** up in the bore. It still runs but i parked it.i dont want it to grenade

this mechanical rpm limit is for protecting the enginge when at full throttle without any load.
Maximum power while cutting should be at a much lower rpm, like 9000 rpm or so !
Just "fixing" that valve will not affect the power while cutting! Excpet you will do some porting job, that ends up at a higher rpm during normal opperation.
The valve also does not alow you anymore to do carb adjustment according to max rpm, just as every rpm-limited saw, you have to do the finetuning while cutting in wood.
As I wrote in your other thread, the 143 is the last saw you want to tune above factory specs! Not very durable even in its original setup!
