Pro Chaser Carburetor 50-640 – Replaces Tecumseh 640084B For Craftsman, MTD Snow Blowers (with HSK50, HSK40)

If your snow blower or yard machine is hard to start, runs rough, or won't stay running, the carburetor is probably clogged.

This is a Pro Chaser carburetor, model 50-640, which replaces the Tecumseh 640084B.

It fits a bunch of Tecumseh engines, including the HSK50 and HSK40 series.

Compatible with Craftsman, Sears, Yard Machines, MTD, and other brands that used these engines.

It's for snow blowers and possibly other outdoor power equipment.

It runs on fuel/oil mix (2-stroke?).

Actually, these are likely 4-stroke?

Check your engine.

It's brand new, comes as a complete carburetor—probably just bolt on and go.

No assembly required.

Made in China, but Pro Chaser is a known aftermarket brand.

It might come with gaskets and maybe a fuel line?

The listing says bundle description yes, so maybe includes extra parts.

If you've been fighting with a gummed up carb, swapping it out is often easier than rebuilding.

Just remove the old one, bolt this on, and you should be back in business.

Good for winter maintenance.

Get your snow blower ready before the next storm.
