Starts ok soon as u try to rev it bogs out die new carb no change checked muffler it ok fuel filter fuel line allok

Have you checked fuel pressure, some time will give you same symtoms. starting vehicle and no load engine runs fine but soon as you load it, it bogs or dies....

May need to have the unit checked. Could be something as simple as a clogged muffler, air filter, fuel filter or engine wear or damage.

Pumping the primer bubble while the engine is running should cause the engine to over fuel and stall (if the tuning is correct). Sounds like its not fueling enough, pumping the primer is forcing fuel through the carb causing the engine to pick up rev's, but this is soon exhausted which is why it wont rev on the throttle.
* Check that the fuel line is not damaged and drawing in air. (if this is intact try the next step)
* Strip and clean the carb. Replace any diaphrams if needed.
* Check gaskets seal between carb, air filter and cylinder.

Just out of curiosity what standard carb settings did you use.?

It really does sound like the exhaust or the spark arrestor is blocked ( or the exhaust port itself is carboned up ) remove the muffler, check the exhaust port, if this looks ok, run the machine with a very slack muffler aqs a test, if ir revs then it is blocked.

take the muffle off and run it if ok open the muffler a bur off the screen inside with a tourch

There are a few things to check, if the muffler has a spark arrester gauze in the out let this may well be blocked, remove the muffler and the gauze, does the engine now rev? if yes either the park arrester is blocked or the muffler itself is blocked, if this does not cure it, check the flow of fuel from the tank to the new carb, replace the filter in the fuel tank and try again, if this does not help try running the saw with the air filter removed, if it revs normally the filter is blocked.

check the muffler for the exhaust being plugged, If not start checking your fuel lines and fresh gas, then fuel filter and ,all esle failes clean carb out.....hope this helps

check carb and clean jets

Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
Chain Saws:
5) check impulse tube and intake boot for cracks or leaks
*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
6) replace gaskets/diaphragms
a) use a spray carb cleaner to clean jets, holes, and body of carb
b) fuel pump diaphragm goes against the carb body,
then the gasket towards the outside
c) metering gasket goes against the carb body,
and the diaphragm goes towards the outside

hi

check the screen filter from the carb,check the assembly needle-spring -lever,check the fuel filter ,check all the membrans and gaskets from the carb,check the sparkplug pipe if it is fit snugly on the plug.
