Hi Troy,

I have a YS160 in an Xtreme Composite Astral XX using a Budd mount with nose ring. This particular engine has been rebuilt by YS Japan. I got the engine back from Mr. Yamada during the CAOCC last year. The engine run fine for about 4 gallons of Coolpower 30%. Then it would start sputtering and sometimes quit when I get to any of the last three meneuvers of P07. I noticed that there was some oil residue on the L shaped tube that goes from the head to the carb at the back of the engine. So I changed the 2 O rings inside the head. No more oil residue on the tube but the rubber part of the mount is still a little wet with what I believe is fuel from the carb and the engine still sputters and/or quits. All the fuel lines seem to be okay. We are having our natioals in two weeks so I have to get this solved quickly. Any ideas on what is wrong? Thanks a lot.
