Help with lawn mower primer bulb.

[Firedog]

Thank you all for your efforts in trying to help me resolve this. I finally found a number to the distributor, who gave me a site and I have ordered the part. For anybody out there with the same Lawn Mower. The website for schematics and ordering parts is https://mecanair.net
This particular part # is SHT_16210-Z250130-00A0 (yes a mouthful)
I hope I can return the help in the future. Cheers
