Chainsaw Repair

A 116Si and a Dolmar 6000i use the same piston and cylinder but the brake is a little different

The 116Si is 60cc and the 120Si is the same chainsaw with 68cc

Maybe slightly more so?

The main difference with the 116S is there is a pressed on worm for the oil pump drive so it has a full time oil pump instead of one that only runs when the chain is spinning like on the 6000.

I think this was more of a EPA thing than of any real usefulness.

The oil pumps themselves on all the Dolmars in the last 20 years that you and I would be using are the same design. from the 111 to the 7900.

The 111/115 also changed to part time oiler when the 6000/6800 came out in '97 and the 116S/120S was discontinued

In '99 they made the 111 the same closed port cylinder as a 115 and I think that was the end of the 115?

Thanks for taking the time to upload and posting that link for me.

Just a stock 116si, with a 16" bar, 3/8" full chisel 7-pin. Probably had a tankful through it before I shot this, so not a fresh out of the box sharpening. I like to run my rakers in the .045-.050 range, and thats about what these are. The wood was Ash, about 14-15" at the big end, tapering to 11-12" by the end of the vid. I am no racer, this isnt a special video or anything. Just the way I cut and run my saws everyday. I have a soft spot for the 116si and 120si.

660mag...you seem to know more about these old dolmars than I do. I have a few 116si's that are ported, and your right, wasnt much that could be done. Just a tad wider, and really just smoothing out casting lines. The few I did, I raised the ports just a tad too, to compensate for taking the base gasket out to get squish down to 0.020-0.025.

Thanks again for posting that for me Cut4fun. I really appreciate it.

Never ran anything but the SI's. I imagine the supers were good runners too, and would snag one in a heartbeat if the price was right. But the 116/120 non-S versions dont interest me.

I wouldnt mind having a 114 and a 119 to round out my collection, but dont see them that often. And I hardly ever use my 112 or 117. The 117 is quite strong, but its no 116SI. And honestly, the 112 reminds me of a 029, overweight and slow

My go-to saws are my 115i and 540 for trimming, and a pair of my 116si's for bucking. And I'll take my 6400/8400 along if I know I'm getting into some big wood. But dont use it unless I have to. Its easier to maintain 16" B&C's than a 24". I really do have a soft spot for the dolmars

Those are some good Dolmars to be going to. I have the 115i, 5105, 6800, & 7900 . . . That gets the job done.
