I recently acquired a briggs and stratton 5hp engine at a yard sale for $5, its problems were that it would only run at idle and made a ticking sound. I took the head off and found that the valve seat had come loose.
Never have I had a valve seat come loose, is this an easy fix or does the whole block have to be replaced?

Model 130202 Type 3104-01 1989 model

I have fixed several like that even the older 8 HP, turn the eninge until the other valve is open, with the valve spring still on the valve that has the loose seat, get a center punch and go around and make small dimples all the way around the seat, punchine into the block area, if you can relap the valve and it will work, Light Mechanic

I don't really like the sounds of this method, but thats just my 2 cents

It's the method recommended by Briggs, and found in their service bulletin!

Pyro, not being ugly but if you are not sure of what is know to work by those who have done it for years and the motors worked fine after that for years, I once learned and never forgot don't condemn what you don't understand, we are all here to help and to learn, I am still learning, Ok, I am ready to take the heat, let's hear it, Light Mechanic
