Question about Garden

1 Answer

I have a JONSERED 2149 Turbo chainsaw. It was working ok until yesterday. I was cutting up timber yesterday and it was working ok for the first 4 hours work then it started to loose power, once there was any resistence on the blade the chain stopped spinning. I was using the same fuel mix as I usually use (25:1) with a standard two stroke oil. There was some oil staining on the exhaust port and some fuel on the air filter when I took the cover off also, not much though.It starts ok and the chain is not too tight or being restricted or blocked in any way. The engine starts to labour when I try to cut the timber, (softwood, fresh timber). Any advice please ? Thanks Gerry

Jonsered 2149 turbo , does any one know the factory settings fornthe carb ? Iv turned the H L in all the way waiting instructions , what about the idle ? Thanx

Yes I do. Do not over tighten the H and L needles you will ruin the needle seats (clockwise closes the needle jet, counter clockwise opens the needle jet) There is no air mixture needle on a chainsaw carb (2 cycle engine) all are gas mixture needles H - high speed operation, L - low speed operation. [The saw carburetor operates like a 4 barrel carb on a 350 chevy, runs on 2 but kicks in all 4 when you hammer it.] Turn the H needle to 1(one) full turn open (counter clockwise). Turn the L needle to 1 1/4 (one and one quarter) turn open (counter clockwise). NEVER EVER close the H needle to less than 3/4 open or the L needle to less than 1 turn open. If you do you will burn the saw up from lack of oil lubrication. [I have several Jonsereds saws a 52E, 451EV, 49SP, 520SP, 621 race saw, 630, 70E, 70E race saw, 80E and last but not least a 90E. I worked many years for the importer and distributor of Jonsereds as a Territorial Rep. All my saws run like a top. My newest saw is a 1984. I chainsaw carve and cut firewood with all of them year round. In short I like-em, they're the best.] I find that all my saws run the best and strongest with the carb set at around 7/8 turn open on the H needle and just above 1 turn open on the L needle. The idle screw I set last after the saw responds correctly to the carb settings. I quick throttle the saw to make sure the saw picks up RPM and doesn't fade out, put in a log to make sure it maintain tourque under load and not bogg down (tweak the H & L if needed, remembering the 7/8 - 1 1/4 rule I adjust the idle screw to where the saw sound smooth and un-labored at idle. I never let it idle to where the chain moves when it idles. For safety reasons. Hope this helps. EdN

I have a jonsered 2149 turbo

Hi Stian:
If this is anything like the chain saws that I know and love, it would get "tuned" on site for where you're running it. (Altitude changes can affect performance).
- Normal procedure.
Start it up and let it warm up..
- With saw running at full throttle, Set high speed to leanest (screw in until RPM drop, then screw in 1/3 to 1/2 turn.
- Throttle back. set idle screw... smooth but chain not turning.
Hope this helps.

The chain on my Jonsered chainsaw becomes slack after just a few minutes use.

The chain on a chainsaw expands during use.This is caused by the heat generated by friction with the timber being cut. The chain should be monitored during use and the slack taken up by the tensioning adjustment screw or knob. You may have to loosen the nuts holding the bar before doing this and then tighten them securely. If these nuts are loose the chain can become slack. If you give me the model of the chainsaw I can try and find a manual and check the tensioning procedure as newer models of chainsaws have either automatic tensioning or have a thumbwheel arrangement for doing this.

How is the throttle cable routed on the 2045 Classic Turbo Jonsered Saw

Hello Chris;
You can find an OM for your saw here:

ArboristSite Chainsaw thread (free to join)
This is a "Jonsered 2045 turbo" thread.

Post 2 (Warroad50), lists your saw in his signature and is active on the site. I think if you join and send him a PM he will gladly snap a photo or 2 of the cable routing on his saw. There are other owners here as well. All I have met are willing to offer a little help when asked. A search for a related subject and posting a question there is usually more fruitful than posting a question that has been asked before.

If you have more questions or need additional help please reply below and I will get back to you. Thank you for using FixYa and Good Luck. HTH
