Chainsaw Repair

The four saws in this series have Kolbenschmidt brand cylinders with the transfer on each side coming out the cylinder wall and going back in to bypass the piston like on a Stihl 660. They also have a windowed piston.

This series of Dolmars are just very pleasant to use. They are a higher rpm powerhead and normally have a 7 pin rim. The rim is between the clutch and the crankcase.

There are two other Dolmars; the straight 116 and 120 (No "S") from the '80's that are close to this design but the bore and stroke and the displacements are different. They are pleasant to use saws also but are not as big or powerful as this later series.

One significant difference between the 120Si and the 6800i is that the 6800 came out after Makita bought Dolmar and therefore there is a corresponding Makita 6800.

The "i" means they have a Tillotson injector carb. Instead of a choke, they have a valve that lets the fuel pump put fuel directly into the carburetor air stream. Often in the cold winter, the engine will start and continue to run long enough to get the injector (choke) turned off.

The "H" on mine means that it has heated handles

Another unique thing about this series of saw is that the oil tank is plastic and actually part of the handle assembly. The muffler on this series can be taken all apart if you take it off the cylinder. But, if you let the muffler get loose, there's a big chance of burning a hole in the oil tank. The one I seen damaged this way had the muffler banged up from being thrown around is the reason for the muffler being loose and leaking out the bottom.

This is my LIKE NEW saw for it had little use to begin with but I found a new old stock 6800 cylinder (No piston) and bought a Meteor piston/Caber rings for it. Then it has the new old stock 24" bar and Stihl RS chain.
