640259 36045A 36045 Primer Bulb 49-085 120-658 Fits for Tecumseh LEV80 LEV90 LV148EA LV148XA Toro 20001 20003 20005 20007 20008 Lawn Mower 2pack

What It Is

This is a 2-pack replacement primer bulb for small engines, specifically designed to fit Tecumseh LEV80, LEV90, LV148EA, and LV148XA engines, as well as Toro models 20001, 20003, 20005, 20007, and 20008. It’s used to manually pump fuel into the carburetor before starting, common on walk-behind mowers and some snow throwers.

Fitment & Compatibility

Before buying, verify the following:

• Engine model: This bulb fits Tecumseh LEV80, LEV90, LV148EA, and LV148XA. Check your engine’s model number (stamped on the blower housing or valve cover). It will not fit non-Tecumseh engines (e.g., Briggs & Stratton, Honda).
• Toro model numbers: Confirmed for Toro 20001, 20003, 20005, 20007, and 20008. Double-check your mower’s model tag—usually under the seat or on the frame.
• Cross-reference numbers: OEM equivalents include 640259, 36045A, 49-085, and 120-658. If your old bulb has any of these numbers, it’s a direct match.
• Physical dimensions: The bulb is about 1 inch in diameter with a small barbed fitting. Measure your old bulb’s diameter and stem length to confirm fit—especially if your mower uses a larger or smaller bulb.
• Aftermarket vs OEM: This is an aftermarket replacement. It works as a direct substitute for OEM parts but may have slightly softer rubber or a looser fit on the stem.

Key Things to Know

• Quality concerns: Rating is 3.6/5. Some users report bulbs cracking or leaking after a season. The rubber may be thinner than OEM, so expect possible shorter lifespan.
• Installation: Easy—pull off the old bulb (it’s usually just pressed onto a plastic stem) and push on the new one. No tools required. Ensure the stem is clean and dry before pressing.
• Common gotcha: If the bulb doesn’t seal tightly, it won’t prime. Try a small zip tie around the stem to secure it. Also, check the carburetor’s primer circuit for blockages—a bad bulb isn’t always the cause of no prime.
• 2-pack value: You get two bulbs for about $6.60, which is cheaper than a single OEM bulb. Keep one as a spare.

Should You Buy It

If you have a Tecumseh LEV80/90 or a compatible Toro mower and need a cheap, functional primer bulb, this 2-pack is a good budget choice. It’s not the most durable, but for the price, it’s fine for occasional use or as a temporary fix. If you want a long-lasting replacement, consider an OEM bulb instead.
