Bolens 8hp. valve issue.

[scaldwellk]

I have an older snow blower with a tecumseh 8hp engine. It seems that the intake valve is my issue for it not running. I pulled the head to take a look at things and found that the intake valve does not close. I can pull up on the valve and it acts like there is no spring on it. I am looking for information on how these little engines valves work. Any help will also be a big help. Thanks.

I just need an intake valve spring retainer and the round cap that goes on the sring with the retainer clip.

Valve is fixed and unit is running.
