The 2 stroke engines,your chain saw as well need to be check every year due to the carbon deposit from burning gases.Check if the engine is sealed properly(gaskets from carb,cilinder,crankcase and the seals.Pay attention at the flyweel key(not to be sheared off)crankshaft,piston,piston rings,piston rod.

How to stop saw from bogging

Two things. First, is the chain dull? Second, if it develops a "throaty" sounds when you're cutting instead of the "crisp" sound you normally get from a chainsaw or weedwhacker or dirtbike... then the carburetor's running rich - it's "four-stroking". Try fiddling with the two mixture adjustment screws; one should be for idle mixture, the other for high-speed mixture. Get the saw idling and turn one of those screws clockwise ONE-QUARTER TURN. If the saw's idle doesn't change, turn that screw one more quarter-turn. if the saw's idle still doesn't change, thats the high-speed mixture screw.

If the saw's idle changes while you're doing that, then you're on the idle-mixture screw - return it to exactly where it was and adjust the OTHER screw clockwise a quarter-turn. Now try cutting - see if you've improved the saw's performance. If it's still four-stroking, try another quarter-turn.

If you go too far, the saw won't want to run at all at higher speeds... so you'd need to back up the screw the other way. Run it at the richest (most counterclockwise) position where it doesn't four-stroke under load.

Generally this is a fuel / air ratio problem. Usually it can be solved by a carb adjustment. On the carb there are usually two screws, one marked low or L , the other marked high or H. Low is your adjustment for idle mixture, high is for mixture at full throttle. The saw should Always be adjusted to run well during the cut. Make adjustments a little at a time, then try The saw. Continue small adjustments untill the saw is performing well at full throttle while Cutting.

When it won't run correctly, try removing the fuel tank cap temporarily. If it immediately picks up, suspect tank venting problems. Good luck!

Check the fuel filter for plugging. Check the fuel lines for decay or other damage. Make sure the carburetor fasteners are tight, especially the carburetor to cylinder fasteners. Did you check the lower chamber diaphragm when you were working on the carburetor? It should be flexible with no holes or cracks. Go to: for a 12 page article on Walbro brand carburetor theory and troubleshooting. This information applies to other brands of carburetor as well. Hope some of this helps!

Carbeurator adjustment. Bogs down under load

Try making small adjustments to the "H" needle. CCW is richer and to rich is better than to lean.

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.

There are 2 wav (sound - idle & full – may not be highlighted) files that I find most helpful, I think you will too.

A plugged up muffler can also cause slow response and cut power. To rich a fuel/oil mix is usually at the heart of a plugged muffler. HTH

Loses power when trying to cut wood

Check the muffler screens first. Then the spark plug. If not the case, then adjust the High setting on your carb. Prolly starving for fuel under engine load. If it is still a problem, Pull the carb and clean it.
