Oh boy. The Fuji is a real clunker, that's why they finally got smart and started putting a Zenoah in them. Expect the exhaust system to break off as it wasn't supported well. The driveline is a real piece of work as there have been many that break free at the propshaft. These things were almost being given away when the Rio 51Z came out, I could have bought a pile of them for $475.00 apiece.

I run 8 oz. of oil per gallon of gas. Actually I've been using Coleman or Ozark Trails campstove fuel and Honda HP-2 oil. Yes, it's more expensive but no nasty gas smell, long shelf life, cleaner burning and no additives that'll ruin diaphragm gaskets.
I've known Mike "GrimRacer" Zaborowski for a decade now before he went to work for AquaCraft. Not until they dropped the Fuji and put in a Zen did he admit how bad it was.
