the valve seat fell out of place.

the head is aluminum. Can I just re install the seat and ping the aluminum edge of the head right next to the seat to hold in place or is that just a temp. fix? Thank You.

The peen repair is controversial. VW and Corvair owners have tried it for decades. I believe the evidence is that you will be back in with the problem soon. Compared with an auto it is easy to remove and replace small tractor heads? So you can try the peen. good luck.

Yes, on the L-heads, it is the way that Briggs outlines in their repair manuals, but the trouble is getting the seat centered correctly. Then
then valve and seat should be recut to ensure that it is correct., most shops are not equipped to do it correctly, so call around.

That was the way Briggs said to do it in the past. Today's engines are running a lot hotter and I would not recommend it if it is an OHV engine. If it would come out again, it could cause even more damage, cylinder and piston, which would call for a huge bill, far more than a new head now.

I have to agree with Rivets on this. If it is a OHV engine you can do a lot of damage if it holds the valve open to the point of hitting the piston. Buy a new head and be safe. A L head I have done it before and never had any problems.

Yeah, I have never done an OHV either, I missed that he was talking about an OHV. I guess I am getting old, stuck back in the good old days
