Small Engines (Lawn Mowers, etc.): Installing a primer bulb, exact configuration, retaining ring

Question
I have a Toro CCR1000 series snowthrower. The old primer bulb fell apart and I have received a replacement.
Is there a trick to installing / stretching the bulb on the primer? Does the top shroud have to be completely removed?
TIA,
Tom

Answer
Hi Tom,

I can't recall the exact configuration of your primer bulb.
Some are held in place by a retaining ring.  Try to describe it to me and I may be able to offer some info.  If something is holding the bulb on now, you will need to remove that and maybe the shroud too.

Let me know what you find.
