A new post on this thread!
I have an engine that looks like the one in the first photos with a few exceptions. My serial number is 7101240 so I'm gjuessing it may be a latter engine. The number on the other side is 0.8cnpy. If 1.0 is an .061, then my engine is an .049. One other difference. My carb is a press fit, with no screws holding it on like my other Norvel, AND it has a small bleed hole on the back of the carb. Is anyone familiar with this? The reason I'm even fooling with this engine is the Norvel I had on my little seaplane would not idle down low enough to allow me to land power on. I'm hoping the bleed hole will help with that.
It appears this is a new, or at least, never run engine. I seem to remember I had a heck of a time breaking in my older one. Can anyone help me with the procedure? Do I run it at high power and let it cool for a little while (Run rich) and then go high again, or what. I can't find my instructions for these engines.
Thanks in advance!
