The dealer could well be correct, if a two stroke engine has an air leak through a seal or gasket, it will draw air through here and not through the carb, this in turn will weaken off the mixture and cause high running at idle, there are other reasons, like the throttle flap is not closing properley, or the throttle cable is not correctly seated, remove the top cover and turn the throttle shaft manually to the idle position.

There are two idle screws one high, and one low. Your high adjustment idle screw needs to be adjusted.

I think a duplicate question… duplicate answer
This thread says a Jonsred 625 is a Husky 61. Post 17 by SawTroll can be taken to the bank. Everyone defers to him regarding specification questions.
http://www.arboristsite.com/showthread.php?t=103127&highlight=jonsered+625
I found an Operators manual here (no IPL):
http://www.tilton.usa.jonsered.com/node246.aspx

There are a number of model 61s starting on page 11. I suggest you contact Husky for clarification of any saw older than 2000. They may even provide the correct IPL for saw (Jonsered owned by Husky).
HusqvarnaUSA.com
http://www.husqvarna.com/us/homeowner/support/download-manuals/
Enter the 3 digit model number (no XPs, Es, just the numbers)
Serial number decode – useful when downloading IPLs and Manuals
06 1500198
06 = year produced – 2006 (single digit before 2000)
15 = week produced - March
00198 = 198th unit Husky produced that week

That said, the 61 has an outboard clutch. This will help you with removal.
R² Drive Link Outboard Clutch by Drivelink.blogspot.com

  1. Check the IPL for your saw to see if any special tools are needed. Poulan clutch removal tool part number 530031112 if needed. Under $5 from many sources,
  2. There are metal piston stops available, when square (almost never) with the piston top these work well, if not square they have been known to punch through the piston. I suggest a length of starter cord or nylon rope be used instead of the piston stop (retain 6" ± so you can remove it). Make sure the piston is near the top of the cylinder before feeding the cord or it can fall through the exhaust port and damage the piston as it rises.
  3. Everyone I have ever removed had a left handed thread (tighten it to loosen it).

I think an air leak and she is running lean. Maybe time for some pressure/vacuum testing. Continuing to tweak the carburetor may camouflage a larger problem until the saw fails.

Those saws are very finicky. First shake the saw very vigorously, as the saw running dry mayy have sucked dirt to the intake screen. Clean the plug and check gap. Prime, choke and pull till it starts. your plug may be foulled, this happens alot when a saw leans out from running out of fuel.

Carb adjustmwnt requires a special tool and a tacho, the saw is set from the factory for the best emmisions, however it may need a small adjustment, this should be done by a qualified dealer, incorrect adjustments can damage the engine.

It's a bit of an art and you have to be able to hear the slight changes in combustion and engine speeds. It took me years to become what I consider "proficient" and not struggle with adjustments of a 2 cycle. You must adjust the idle air/fuel mix first, then high speed. I read improper instructions regarding this all the time. The low speed circuit has to be set first because it changes the overall mix when high speed is open. Any changes in low speed air/fuel mix affect high speed (not the other way).


Start by remove chain. Begin with both H and L screws at 1 to 1 1/4 turns out. You want the idle speed high enough that it runs well enough to get through the idle mix adjustment without dying, but not so high that the carb high speed is opened. So if its dying while adjusting low speed, increase the idle speed. If you can't get idle adjusted without it dying, then likely you have other issues with the carburetor, spark, compression (crankcase seal) or even blocked spark arrestor screen.


Once you have low speed adjusted, you begin on high speed adjustments. See instructions. If the saw does not want to accelerate without stalling and you have opened the high speed screw, then likely the high speed circuit is fouled or there's a crankcase leak.

How to adjust the idle speed on 1992 Dodge Ramcharger?
Its not really adjustable.
The computer controls idle speed via the idle air control valve.
You probably have a vac leak.

I have a 450 farm boss 50.2 cc how do i adjust the carb.so it will wind out to high speed
sounds like you should check the spark advance before adjusting the carb. As an engine accelerates, the timing of the spark must also adjust to occur sooner during the cycle.

My stihl ms 260 chainsaw wont idle down to low idle
High idle is usually a sign of running too lean, or having an air leak around the carburetor mount, or even somewhere else on the machine. if turning the low mixture screw out half a turn or so doesn\'t help, I\'d start looking other places for a leak.
Check things like the plastic plate the carbie mounts to (intake manifold) and all the gaskets associated with that area.
Also, check your fuel lines aren\'t perished, they can cause air to suck up into the carbie and cause issues.
If you still have no luck it\'s possible one of the main crank seals may have gone, causing air to suck in around the crankshaft.
This is best left to a qualified small engine repairer to replace, as they can be dicky to get in there without damage.
Hope that helps!

I have a 757C chain saw. When I start it, it idles rough for a couple of minutes and then once it warms up runs fine. I put a new carb on this saw and have adjusted the high and low speed needles. The
did you replace the crank seals ? The seal goes out on the crank next to the clutch,it's called a grease seal, it loses the suction needed to pull fuel in to the engine, can be a tricky one to replace, but will spark a new saw back to life. You may want to replace both crankshaft seals

Hello, i have a stihl ts400 and i just rebuilt the topend(crank,piston,cyl,all bearings and seals.Fires up easy, idles fine,revs fine, but when you hold the throttle down it doesent want to hit rev limiter...
There is not an actual rev limiter. The top end is controlled by the carb. You actually want it to sound a bit rich at full throttle so that it has enough fuel when cutting under a load. What causes me some alarm is the revving up part. If it revs too fast that is a lean condition and can quickly ruin the piston and cylinder much like running straight gas. A torn intake boot can cause this. The high speed spec for the TS400 is 9,600 rpm + OR - 500 RPM. Your saw may not have a needle to adjust the high side as some have only the low speed adjuster. Also when you disassemble and clean the carb always use a new kit with the gaskets and diaphragm. Any Stihl dealer can furnish the kits and they aren't terribly expensive. Often between $10-20.

Tk carb ? sthil trimmer has 3 adj screws ,how do you adj?
One adjustment screw (probably Phillips-head) is the Idle speed adjustment screw. Turn it in, to increase idle speed (it moves the throttle plate)...turn it out to slow idle speed down. The other 2 screws are the Low mixture screw and the High mixture screw. The L screw is closest to the engine and is used to adjust the engine at IDLE. The H mixture screw is to be adjusted when the engine is at wide-open throttle to get the proper RPM's....not too little and not too much. Here is a tutorial by Zama carburetor reiterating what I have just told you and HOW to go about your adjustment.

Carburetor is running rich.
Hi jim paton...
You may have some trash/debris in your jets that is causing your engine to run rich, or maybe some did not adjust the high speed/idle adjustment screws properly

Before you remove or try to adjust your low and high speed jets you should always count the number of turns it takes to lightly seat the idle mixture screw and high speed needle adjusting screws.
Be sure to write the number of turns down on a piece of paper so you will know how many turns from the seated position to open the jets when you go to reinstall them, or if you remove them for cleaning or replacement.
Normally you will adjust your idle jet to 1/2 to 3/4 turn open from the bottom seated position.
Then you will re-adjust the low speed of the engine when the engine is warm by turning the idle screw in or out till the engine runs smoothly at idle speed, around 1200 RPM.
The high speed jet is adjusted to 1 1/2 to 1 3/4 open from the bottom seated position, after the engine is warm.
Then re-adjusted by turning the High Speed jet adjustment screw in or out till the motor runs smoothly at high speed.

I have a 99 road king 1550 fuel injected. on the way on a trip the engine lost power and shut down . cranked but no start. Took it to harley dealer where they found that the computer was fried, front...
Interesting story but other than the low idle, you never said how the bike was running. I must assume that it's running alright other than your concern that it may be running lean due to your fuel mileage. You're mileage is about nornal for an engine as large as yours. My 1340 Evo gets about 45 miles per gallon. If you had a vacuum leak on the manifold seals, you would notice it mostly at idle speeds. The idle speed would probably vary considerably while sitting still. It may even cause one cylinder to miss. As long as your bike seems to be running good, ride it and enjoy it.
