you either blew the head gasket or a valve seat popped out. your going to have to pull the head off. if its not a steel gasket you need a new one.

thanks for all your help on getting my mower back to run, what happened was a valve seat had popped out so what I did was pop it back in and it fired up.

well i whwent to go mow the lawn with the mower today and it did the same thing, the valve seat popped out again, when I had the head off, i noticed the area around the valve seat was scored up, so do I need a different head to correct the problem, becuase the seat keeps popping out.

once it pops out thats it. thats a bad design on briggs part. if you just push it back in it will just pop out again. you can try this, but if it doesn't work you need to get another engine, or a short block. get a center punch and

and prick punch around the seat after you push it in. the prick punching will push the aluminum tighter round the seat, in turn holding it in. it does work, i've done it before, but there is no gaurantee that its a permanate fix. it does work for awhile, if done right.

i see i was the only one who new about valve seats popping out on brigg's. i think i've been doing this for too long, and i'm only 26
