SOURCE: Require high and low carb settings for Poulan 2050

You will find that saws of recent production allow very little if any adjustment for the consumer. The carb will either have limiters which allow you less than one turn of adjustment or they require a special tool to make the adjustment. You will need to take it to a dealer to have these adjustments made. This is your government in action protecting you from that evil pollution your chainsaw spews out.

If you are able to adjust, then gently seat each screw and open 1 full turn. This should allow the unitto start and you can adjust from there. If it will not start you probablu need carb repair or replacement or you have other problems.

SOURCE: sachs dolmar over oiling chain

I am not familiar with your specific saw. That said on most saws, under the clutch cover, below the clutch is an adjustment for the oil pump.

SOURCE: high & low carb needle settings

I would start with both the "H" and "L" needle valves at 1.5 turns CCW from lightly seated then adjust for performance as follows:
Carburetor Adjustment by Madsens.com
http://www.madsens1.com/saw%20carb%20tune.htm

  • CW is leaner; to lean will destroy the saw. If over tightened closed (CW) the adjustment screw faces are easily marred; marred adjustments are difficult to impossible to set properly.
  • Clean the air filter; adjusting with a dirty filter can cause a run lean condition once cleaned and the saw run.
  • Clean the spark arrestor and muffler; if the saw cannot exhale it cannot inhale.
  • There are 2 wav (sound - idle & full - may not be highlighted) files that I find most helpful, I think you will too.
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

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.

Dolmar 6800


The idle speed should be NOT QUITE high enough to rotate the chain when the chain lock is not engaged. There should be NO adjustment for high idle speed.

Throttle trigger will not lock


1. Make sure dead mans handle is fully depressed
2. Squeeze throttle in
3. Push choke switch all the way down
4. Pull saw over till it fires
5. Click choke switch up one position to half choke
6. Pull over saw until it fires up, saw should start running at high rev's
7 .'blip' throttle for saw to return to tick over.

If the choke switch doesn't stay down in section '3' check chokelinkage to carb.

Got a1996 yamaha yzf 600 and it starts but its not getting gas so it shuts off new carb all the way thru


Hi, Ktatejr86 and the usual suspects are:
1. Fuel cap or fuel tank is not venting properly.
2. Fuel filter clogged.
3. Fuel line pinched or kinked.
4. Float needle and seat sticking.
5. Float level too low.
6. Carburetor bowl vent line clogged/blocked/pinched.
7. Idle adjusting screw set too low.
8. Air/fuel mixture screw set too lean.
9. Idle port, transfer ports, slow air jet clogged.
10. Slow fuel jet clogged.
11. Faulty fuel pump.

Factory carb settings for dolmar ps460 chainsaw


Try squirting a little starting fluid into the carb and try to start. If it will try to run, you have a fuel problem. Try changing the fuel filter first.

1964 5 1/2 hp evinrude kills at high speed


You should have a High Speed carb adjust and a Low Speed carb adjust. If it's running fine while idling, adjust the high speed setting. If you have two nobs, its the lower one. May be set wrong. If you don't have two nobs, remove the carburator and check the jets to make sure they are completely clean or better yet, order yourself a carb rebuild kit to take care of all of this. I just rebuilt my 1971 evinrude 4hp and the carb kit made the world of difference.

Gas engine will not start without pulling trigger on wand to relieve pressure-engine dies when letting off trigger


I am afraid that is how they work even electric ones wont start unless you squeeze the trigger ,once they are running you should be ablr to release the trigger , and then squeeze it again whilst running . if yours dies when you release the trgger while motor is running -----good chance you are working at too high pressure. but to start you have to release all the internal pressure
