I took the back plate off and saw the bearing behind the big end is totally rusted. This motor is 9 months old. The salesman that sold the motor and 10% Cool Power fuel told me I dont need castor or after run oil, well this is patently wrong. I have been reading on this forum around the castor versus none camps and I had to learn the hard way. As I am new to this sport I relied on my LHB to guide me but it is painfully obvious that I should have taken heed from the gurus here on this website. I dont think hovering has caused the rust. Question: How do you apply after run oil when your engine is in a cowl and do you think my LHB should fix the motor even if it might not still be under guarantee?
