Chainsaw Repair

My 6800 has a 20" X 3/8" RSC and a 7 pin rim. The bar looks like a Oregon Power Match - little angled oil holes and all but it says Dolmar. I assume it is original but I didn't know they had the tiny angled oil holes in the late 90's? The bar is not the current Dolmar graphics with the little square design that fades away at the tip like on my 7900's and 5105's.

The 6800 is 49mm bore X 36mm stroke

The bar is small mount Husky.

To go along with what RMS61Moparman and Old Iron Logging said about the starting characteristics of the Dolmar "i" series chainsaws . . .

I went to start my 6800 this morning around 9:30 with the temperature around 35F and it started 1st pull and had not been run in 4 days.

After it had run 5 seconds or so I turned the choke and the fast idle off.

Just for info I have a couple of NOS 6800 pistons.
Shep

Used the 6800 Dolmar to drop a diseased Black Ash (emerald ash borer) that was about 18" DBH and 50' high. The drop went flawless. Was guided by a 7/16" Dacron polyester double braid rope attached to my 4WD truck due to being adjacent to the triplex electric service drop. The wind was in my favor for the drop. The top quarter of the tree was dead and shattered in hundreds of pieces when the tree hit the ground. The faller had a safety helmet because of the dead limbs, chaps, and gloves. I did the truck.

Went to do the stump and the Dolmar quit on me about 1/4 through when I backed off the throttle. Couldn't get it restarted readily so I finished the stump with a Husqvarna 365 Special - I have CAD.

Cut4fun stopped by and cut up the trunk with the Husqvarna 365.

After everything was cleaned up, the Dolmar 6800iH started up 1st pull with the choke off so it must have been flooded?

The limbs were mostly done with my Dolmar 111i W/3/8" X 16" that I put the Brison model airplane engine cylinder and Meteor domed piston in. I also had a Stihl ported 026 W/3/8" X 16 and Stihl 025 four port, MM'd, W/.325" X 16" that I personally used just to give the saws a little use.
