Default Seal Orientation

I am curious to know if the little hole (Puls Port) on the on the (ZDZ Super 80) crank case needs to be completly covered by the seal. Right now it's a tiny bit open and I can hear air moving thru it when turning the prop. From looking at the seal I can imagine that the little thicker part actually (Pic 4) should be facing so that air is only passing thru the little hole on the carb and not behind the seal.

It's the first time that I had the carb off. The engine is basically brand new, less than 30min total runtime. Could that be an assembly failure by ZDZ?

The insulator (black piece) was installed upside down. Your picture #5 is the correct orientation.

Thanks Jedijody

That's what I pretty much concluded. May have been also the reason why this engine took soo long to draw fuel and start....

Oh yeah. Always reading about the 5-5-1 method. For me it felt more like 50-50-10. Will see how it works out after I turned the insulator around. Maybe all the other users should check theirs as well if they bought it within the last two years.
