[AT] 16 HP Onan twin

[Cecil Bearden]

Replacing the seat is not that big of a deal.   There is a cement that 
will work to glue them in.  If you can remove the seat and clean seat 
and block, then use the glue Loctite something I think, then use a fine 
center punch to raise the metal around the rim of the seat then peen it 
back down.  I have worked on a lot of Onan Engines...  They were the 
power units for brush pumper units.... Steve W might jump in here too as 
I am sure he has repaired some..  Steve????
