Chainsaw Repair

Appears to be a early model Sachs-Dolmar 109, 110, 111, & 115 family chainsaw. These were different displacement variations of the same family of chainsaws. Some parts will interchange between the different models. They all look alike. 1989 ish

The 111 & 115 are 52cc or a little over 3 cubic inches. In the early models, these two differed by the 111 had open port intake transfers and the 115 had closed port transfers. 44mm bore

The 109 & 110 are 43 cc. They also differ by the open and closed port transfers. 40mm bore

All these had the same crankshaft with a 34mm stroke

This saw is a Sachs Dolmar 112 ... 51cc.  I have a clean one that I had ported by a fellow on the Cumberland Plateau.  Runs very nicely.  Here's a link to the info on the Acres site: 

Ha! That was the first time I've used photo bucket, so the slide show thing was an accident. About the saw, the brake is missing and it needs a carb kit. He got it in an auction with some other saws and asked me to look at it for him. I need to find out how much the brake parts would be. It runs right now but needs the carb kit but if it needs a top end are there big bore kits for it or do top end parts from that family of saws interchange? Other than pulling the jug and measuring the bore is there a good way to figure out the model, like numbers cast into it somewhere? Thanks for the help.

They were very good saws, I am keeping my eyes open for similar locally. Parts are getting scarce and rather expensive, you might do better looking for a donor saw.
