How to adjust carberator on blower 358.794650

Check your kill switch. I've seen them short closed and effectively disable the coil. Tear down enough of your blower so you can follow all of your electrical connections and inspect the wiring.

there are several other issues that can relate to a 2 cycle not starting.
crankshaft seals
plugged exhaust
burned up piston/jug assy
you need to investigate a little further before you think you need to adjust something...

if you didnt change anything on gov dont start now.
you may have linkage in wrong hole
or bent linkage , or missing spring

Some Husqvarna carbs require a special screwdriver to adjust them, some just use a mall flat head tuning screwriver.

Screw both H and L screws in. Then turn them out anticlockwise the following amounts to return them to standard.

H 3/4of a turn L1 full turn (Chainsaws)

Some equipment like blowers and strimmers are:-
H 2 1/4 turns out L 2 1/4 turns out

I would check the intake gaskets to the head first. It is possible that you have a leaking gasket or seal affecting the performance. Your snow blower is set to run on the rich side so it will actually run with the carburetor hanging loose off the side of the motor before it quits running (happened on my Toro 421). Try a top end gasket set and a carburetor clean first (could even be a leaking head gasket). All of which I am sure you can handle yourself.

check main valve in carberator for dirt adjust main feed needle close and open to 2 full turns and adjust from their for max power

sounds like its not getting gas in the carberator yet. even though its new i would take off the air breather and pour a small amount of gas in airtake. this might get it started enough to prime the carberator and draw the gas on its own.

Hi
This is either a clogged muffler or carb. Take the off and see if it will rev. If not you need to clean carb and install a carb repair kit. Do not run long with muffler off.

Close both the high and low speed air screws (clockwise). Reopen each 1 1/2 turns
