My son-in-law got the opertunity to run my engine first. Went I got home from vacating we ran it again and I was totally impressed with the starting ease, transition and the way it sounded and idled. BUT, when I installed it, it wouldn't continue to run. Just wouldn't do anything right. It's in a vector flight 300 which requires the tank be installed upside down. WELL,, I pulled it and sure enough the tank was in wrong. Installed it and tried again and it ran better but still not just right. I noticed that the tank had leaked a little from the vent tube and fule tube also. Not sure just where but there was fuel present. So we went ahead and tried to maiden it but it would die on taxi so I said forget about it, it ain't happening. It was an old tank out of his plane because the Tetra tank I ordered was too long. I pulled it when I got home and there was fuel on and around the fittings again so I ordered another Tetra from Central Hobbies. I have put everything back to original settings. High speed at 1 1/2 out, low speed at 1 1/2 out, and other thing flush with body. Anything else I need to do?? Do I need to use tywraps on the fuel lines? The Tetra tanks tubes dont have barbs. Will they stay on without tywraps? How long should I leave them? Here's a pic of my setup as is. It's really not as messy as it looks in the pic. I have filters in both tees, in the fuel line, in the can, in the tank, and on the fill tube. I'm using 20/20 YS fuel. And the glow plug from CH recommended.
