Chuck,
I guess I should have worded it a little differently. Yes you are correct on what the manual states, I was giving the first items listed and doing it without using the exact wording, then I gave what I and allot of other people are doing without giving us any problems. Yes 15% will work and a castor/synthetic blend is acceptable, but I found that fully synthetic seems to be a little better and the 30% nitro mix will make the engine "purr like a cat" at least with my engines.
I just wanted him to see that his problem could have been a lean run along with serious overheating, as well as maybe using a fuel that may have had not enough oil content which could also casue the overheating. The otherside as I stated is it simply could have been a bad sleeve to start with and no one did anything "wrong". In any case, I feel the damage was done prior to him making his runs since he only ran a tank and a half when the problem came about.
I even tried to cut and paste from the pdf file I downloaded on the Saito Singles and it is locked, at least Acrobat Pro 5 will not let me do it. Maybe version 6 will. So since I am at work and today my time is somewhat limited I simplified my response.
Basically, I gave him my opinion on the problem, gave him several different things that could have caused it and then provided an alternative.
Sorry if I gave confusing info.

I do stand by my opinions on the oil type, content and nitro recommendations I gave
