See if the saw has a low speed mixture screw and try turning it out a quarter turn.

Settings for mixture screws


Most Chain Saw Engines Have Three Carburetor Adjusting Screws:
1. Idle Speed/Throttle Stop - This is the adjustment that controls how much the throttle valve (butterfly) stays open when the throttle trigger is released. If this adjustment is set too low, the engine will die when the throttle trigger is released. The throttle valve (butterfly) simply cuts off the supply of combustible air/fuel and the engine stops. If this adjustment is set too high, the high idle speed will cause the centrifugal clutch to engage and the chain will run. This is a dangerous condition and should never be allowed.
2. Low Speed Fuel Adjustment (marked L on carb, this is the low speed jet)- This is the adjustment that controls the proportion of fuel in the combustible air/fuel mixture at idle speed. An adjustment that is set too rich will cause the engine to load up and die at idle speed. A mixture that is too lean will starve the engine and cause it to race or surge. An extremely lean adjustment will cause the engine to die, too.
3. High Speed Fuel Adjustment (marked H on carb, this is the high speed jet) - This is the adjustment that controls the proportion of fuel in the combustible air/fuel mixture at cutting speed. It would not be accurate to say that this is the most important setting, because all of these adjustments need to be accurate for a saw to perform its best, but this is the adjustment that determines how the saw runs in the cut. An adjustment that is set too rich will not allow the saw to reach the RPM level necessary to build maximum power. Throttle response may also be sluggish and the engine would smoke and perform poorly. A mixture that is too lean will allow the engine to reach an RPM level where bearing failure and cylinder seizure are likely. It will also lack power in the cut and tend to run very hot.
The preceding information briefly explains rich and lean running conditions. It also identifies the three adjustment screws and their function. It should be noted that some chain saws lack the high speed adjustment needle. These saws have what is called a "fixed jet" which is set from the factory. "Fixed jet" carburetors are used to prohibit the saw operator from setting the adjustment too lean and damaging the saw. Unfortunately, they also often prohibit the saw from achieving maximum performance.

Hi, I have a Mac-3200 and need to know where to set the 3 carb. screws at. T, low and high I don't have a manual Thank you. Z-man


Most guys adjust them 'by ear'. Warm up the saw (hopefully you can get it to start), and set the high speed by opening the screw until it sounds like it is 'burbling' at wide open throttle. DO NOT adjust until it is screaming at its highes attainable rpm !!!! If you do, the mixture will be so lean it will damage the saw under repeated heavy load. Leaving it 'burble' at WOT (wide open throttle) will ensure that proper lubrication will be available in the cut. Under load, the burble will disappear and the saw should pull strong and not overheat, damage the piston or score the cylinder wall.

Next set the low speed screw until there is no hesitation in rpm increase when the trigger is pulled. Some suggest setting the low speed first then the high speed so you may have to readjust the high speed once the low speed is done.

The idle screw should be adjusted to where the chain is NOT rotating the guide bar at idle. If it continues to move, the idle is too high.

Carburetor adjustment


Generally if you will set the screws about 1 1/2 turns an choke it on start it will go if everything else is ok. The set screws to proper idle an high speed run. Those are very cranky saws so take a few aspirins it might help. Lol

My Homelite ZR10926 16-Inch 33cc Ranger it is starting, idling, it dies when I accelerate it. I assume is the carburetor, maybe ? thank you.


It probably is not getting enough fuel. Check the filter in the tank. If it has been sitting with stale gass this filter plugs up.
Try running the engine with some choke. If this helps, try adjusting the carburetor high speed screw.

How to adjust carby settings after rebuilding. McCulloch Eager Be


Turn both jet needles CW to stops (lightly), then back out each CCW 1-1/2 turns. This is a basic setting that should allow the engine to start and run. Start the engine and allow to warm up, then pull throttle full on. Adjust H needle CW until the engine starts to speed up, but continues to 4-stroke. Proper setting is when the engine 4-strokes unloaded, but immediately 2-strokes when cutting. Release the throttle and adjust L needle CW for better idle, yet allows the engine to 'follow the throttle'. Adjust idle speed screw so that the chain stops turning, but the engine continues to run. Hope this helps!

Mcculloch 3516 chain saw, does not always start.


It must have spark, fuel and compression to run. Your task is to figure out which is missing.
Sometimes electrical components quit operating once beyond a certain temperature. Does it always start cold and become tempermental when warm?
IMO most hard start problems on a chainsaw with a good fuel delivery system are flooded.
Start Procedure
Cold:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4)
  4. Set compression release – optional step even if saw is equipped with a compression release
  5. Push (open) choke pull starter until it starts. (usually first pull)
Warm:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws) - Don’t pull with choke closed.
  4. Push (open) choke, pull starter until it starts. (usually first pull)
The 3516 is a MTD McCulloch (Chinese). These saws are in a class by themselves. Good Luck

Idle is off??


hi leobowdy

disassembly the carb and carefully clean it.Check the air filter,the fuel line and fuel filter,check the needle,lever,small spring and the screen filter from the carb.Check the sparkplug.
high speed H=2 turns,low speed L=2 1/2 turns,adjust T
When chain saw starts adjust H,L and T accordingly.

cheers savumihai71.
