Product Information

Classification: Part

Weight: 0.01 lbs.

Shipping: Ships Worldwide

Description:

Genuine OEM replacement primer bulb for engines with a pulsa prime carburetor. This part is sold individually. It includes the Rubber Bulb and the Plastic Collar to attach it. A primer sends gas into the carburetor so it can create a fuel and air mixture that is ready to go right into the cylinder and keep the engine running. Over time a primer bulb can dry out and crack. If the bulb is damaged it will not create suction and will not function as needed, therefore it will need to be replaced.

Primer bulb replacement

The buld arrived in good condition, and within 3 days of my order. Unfortunately, it seemed hard to put back and I damaged the rubber (a small tear in the rubber, the tool slipped) and it would not develop pressure as needed. I removed the new bulb and replaced it with the old one. Mower works.
