Please post the model and serial numbers for the engine and unit you are working on. To answer your question we must know the year of the engine.

There are no individual parts available for that carb. What exactly is wrong.

Try removing the main jet and make sure the orifices in both the nozzle and jet are completely open. Run a piece of tag wire through each hole. I use my micro number drills but most individuals do not have them. DO NOTUSE TORCH TIP CLEANERS!!! You will find this jet in the pick up tube, center of the carb. I’ve got special screwdrivers to get at it, but you can make your own by going down the taper on an old screwdriver from your tool box.

I have had good success doing two pro-active maintenance practices.
Try installing a fuel tank shut-off valve, then run the snowblower dry after every use and use ethanol-free gasoline.
