Its the exhaust valve. Finally got to do a leak down test and the upper valve was leaking no matter what I did.
What I am now thinking about doing is buying a used mower so I get the yard cut and keep the neighbors at bay. Then pulling the head and fixing the valve and then sell the Cub (or keep it and sell other mower). Looks like I can get the whole head for about $125..........Thinking about it.
Thanks all for the help.
