SOURCE: my 21 HP diesel zero turn mower starts blowing black smoke

Looks like you've got a good idea on what makes diesels smoke, so I'm sure you know that black smoke is almost always from too much fuel for the air that's going in. So it can be too much fuel or too little air. If your filters are good, the next things to check are the fuel pressure and the injectors.

I know diesels, but I don't have any specific experience with lawn mowers (kubota?). Since it stalls eventually, it sounds like it's not a single cylinder (although not for sure) so I'd check injector pump first.

Hello Chris;

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.

You adjust the T screw at the carburetor. Don't adjust the L or H unless your having performance problems.

My jonstred chain saw has no choke lever


Ian Duncan...

I have no idea if you are bragging or complaining...

I WILL TELL YOU ... I have started many many a chain saw... and the chokes are nearly useless...

FIRST RULE: always use only fresh fuel...!!

Proper sequence for an ice cold saw (optimal adjustment)...
- squish the fuel bulb a couple of times
- set the choke
- couple of yanks until it coughs...
- completely release the choke and the next yank will get you running

If you have NO CHOKE... JUST leave the THROTTLE ALONE
until it coughs... Then start juicing the throttle...

What's a jonstred? Oh... Jonsered

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.

Jonsered 2141chainsaw carburetor adjustment.


You need to set the mixtures for the carburetor. You will find a Low and High adjustment screw. At idle turn the screw in or clockwise until the rps starts to decrease. Then start turning it out till you hit max idle rpms. Turn screw back in a quarter to half turn and it should be idling smoothly. Be careful here and get someone to hold saw if necessary but hold in throttle to full speed and do the same with high adjustment screw. turn it in till rpm starts to drop then back it out until you get to max rpm and it won't go any higher then turn it back in a half a turn.
