Ordered parts today.
I was going to order a nitro HS needle but they're out of stock!
No maiden this weekend!!!

I read in an earlier post here that putting an inline fuel filter will help eliminate the small air bubbles. That's what i did. I installed the GX-40 on my Escapade yesterday, no flying yet. Our club is having an electrics-only fun-fly this weekend.
I also received the new HSN o-rings from NV Engines today and installed it on the short needle and needle into the engine. I will have to tweak it again now that it is installed on a plane and with the different needle.
