Great i have a Saito FA 91S bought in 2004 ready for break in in order to be mounted on AT6 Graupner. Just a question : i have a 14x7 APC propellers, will it be right for the break in as you mentioned a 14x6. Thanks for your videos.
Hello, i have two questions. 1. how does the oil from the fuel get into the crankcase? And 2. How do you know how much torque you should put on the screws after taking the entire engine apart?
The answer to your first question is as a by product of the combustion process oil remains. This oil gets moved through the engine via capillary action, through the valve train. I cannot give a better answer than that really as I am not an engine designer. Nevertheless oil DOES migrate through the engine. As far as torque on fasteners, there standards for torque based on screw size and thread pitch. If you search the internet you will find them. However I never have used a torque wrench to tighten fasteners on any glow engine I have ever owned. It comes from experience and feel. Some people can easily feel the right amount of torque on fasteners, some cannot. I can because I have done it all my life.
Another question, may be coming in part 3 : you ran at 6000 rpm/mn during 6'20'', should we do another run at this level for same time before leaning the HSN since the manual says 10mn ? thanks
Thanks for doing these videos. They help a lot of people .
Break in process could be boring for some people, or very entertaining for others, this keep calm my thirst to run engines.
Beautiful, as usual 😉👍
Great fun there Dave. One flip start and a nice steady rpm. God these Saito's suck!
Most importantly... what’s with the cat picture in the top left 😂

I chose a 14x6 just because I plan on using that prop for other run videos.

When unfamiliar or inexperienced with breaking in engines, yes you should follow what the manual states.
