On second thoghts, why run it on the rich side, why not try tuning it to perfection???

fuel helps cooling, oil helps ring seal and lubrication....running a little on the rich side wont hurt a true work saw....running a little on the lean side wont do it any good....On second thoghts, why run it on the rich side, why not try tuning it to perfection???
Cheers Dean.
tuning out of wood is ok but not perfect and tuning in wood is a little harder...tuning itself is one of things if you dont do alot you may not be hitting the sweet spot...

Sthil 066/660 or husky 2100????

Running it on the rich side can foul the plug & decrease the exhaust port & produce more smoke, the saw wont be running at its most efficient & therefor lose a percentage of power.
But yes, this is preferable to running it on the lean side.
Correct me if Im wrong, but I was taught to (with the high speed adjustment whilst at full throttle.) turn it both ways until u can hear it going out of tune, then centre it, then slightly anticlockwise once more to just b4 the point where it starts 4 stroking again.
Cheers Dean.

there are many variables to tuning. I use a tach as I dont trust my ear for 4 stroking...
changing the fuel oil mix will change tune,
dirty airfilter or clean airfilter will change the tune
different bar and chain length and type of chain will change the tune
etc etc etc etc.
always tune a saw with full kit, ie top cover on, bar and chain on etc etc
yes running rich can foul things, but I am talking about running it only a touch rich for safety sake...none of my saws run restricted mufflers so clogging them isnt a real problem....if your worried about loosing power by running a touch rich, just mix at 40-1 instead of 50-1 and run 98 octane with a high quality oil....and tune to suit

2100 man all the way a legend from the first day of production i thought i had some pics on here but i cant find any ile have to stager out to the shed later and get some pics when i get a chance. alot of this tuneing caper is geting a little off track your average domestic saw as most of you will have are not to particular in there state of tune un like a pro type saw that can change in a simple change of altitude ie working in a valley in the morning and top of a hill in the arvo. but at the end of the day you wont foul a plug un less your way to rich or not working the saw hard enough a bit more fuel wont hurt remember there air cooled and could be working flat chatfull full load for up to a minute or more

2100my username on alot other forums is Husq2100
I have a few of these...3 stock, and 1 that needs to be built for race. Also more than 1/2 the parts to build a complete NEW one....
what mods have you done for racing? what class do you race in?

ported expansion chamber had a modded carb too but thats been lost in the moves around the country . the old man built it with a bloke from husquvarna and raced it with a bit of success it has not been raced since probly the late 80,s the old man won some dealer of the year thing back in the early 80s and had alot to do with the brand in Australia plus various trips to Sweden we sold there bikes as well that enplanes my love of vintage husky bikes as well
