Hi guys,

A couple engine questions for the group (this is for a O-290
installation in a 235 airframe):

o  Is it allowable to install more than one exhaust gasket
   between the engine and the exhaust pipe flange?  I've got some
   real clearance issues between the one of the pipes and the
   bottom of one of the cylinders and a second gasket would be
   the perfect spacer.

o  I've got baffles wrapped around the bottoms of all cylinders
   (to keep the cooling air in the fins longer), but I've found
   no guidance on how much of the cylinder bottom should be
   exposed for the air to exhaust from.  Any good rules of thumb?

o  And out of curiosity, how many of you have primers installed
   on normally carbureted engines?  And if so, how many cylinders?

Thanks, as always, for any help.

Scott Richardson
235/290
