Hello:

The Carbuertor Throttle is Held in the Full Open Position Until the Engine is Started and Running, then the Governor and Spring Work together to Keep the Engine RPMs to the Desired Setting.
The Following is an Explaination on How the Governor System on Small Engines Function.
>>The Governor System behaves like an Unending Tug of War between One of Two Governor Springs, which Pull the Throttle Toward the Open Position, and a Spinning Crankshaft, which Tries to Close the Throttle. When the Load on the Engine Increases - a Typical Example is when you Move your Running Lawn Mower from the Driveway to the Grass - Crankshaft Revolutions Drop. But the Governor Spring is Still Tugging, Causing the Throttle Plate to Open. In Response, a Larger Volume of Air-Fuel Mixture Enters the Carburetor, Increasing Engine Speed to Compensate for the Increased Load. The Crankshaft Speeds Up, and the Tug of War Resumes, until a New Equilibrium is Achieved. With Each Change in Load, the Tension Between the Governor Spring and the Load Brings about a New Equilibrium, known as the Engine's Governed Speed. Neither Side Wins until the Engine is Shut Off. At that Point, without the Crankshaft Spinning, the Governor Spring Pulls the Throttle to the Wide-Open Position. Two Types of Governors are Common on Small Engines - Mechanical and Pneumatic.
Please, Do Not Hesitate, If you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance.
Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Be Happy. Thanks.

Good Luck

Respectfully

SOURCE: I have a husqvarna 55. I put in a new carb, coil,

If you are still having problems I would check or replace white grommet inserted into cylinder and connected to manifold,they have issues with breaking or blowing out.This model also has problems with the black intake boot not sealing around cylinder and manifold,an easy check by spraying a LITTLE carb cleaner around problem area.

SOURCE: i need to set carb adjustments on a 55 husqvarna

I would start with both the "H" and "L" needle valves at 1.0 turns CCW from lightly seated then adjust for performance as follows:
Carburetor Adjustment by Madsens.com

• 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.

It seems that Mac engineers could have come up with something better than the M.M. kluge that they did. The problem is hooking the wire link to the plastic hook on the trigger plastic casting while juggling the front case and engine body. It appears that it should just snap together, but knowing how plastics get with age, it would appear that the trigger should be replaced every time the case comes off. I had trouble with mine and wound up straightening out the wire link end somewhat to force the parts together--it continues to work though. Hope this helps!
