Re: Briggs and stratton 15.5HP IC- Valves not opening
I would take the head off, and see if the rod is bent. They could just need lubrication if the mower was sitting. Are they stuck open, or closed?
Could be a lot of carbon build up. Sometimes you can tap them free, by applying lubrication after each tap.I would still take the head off, and give it a good cleaning, and see whats going on.
What's the model/type/code?... Look on valve cover near the flange, vertical shaft it will be facing up on valve cover. Example would be 31C707-0230E1 040521ZF Keep us posted.
