Yea, thanks. You're right, it is hard to tell about the fuel tank height in relation to the engine. The tank looks like 1/8" lower, maybe level with the engine. The only way I can change the height is a smaller tank or maybe reshape the floor of the tank so it sits lower. It's something to keep in mind though if I can't get it ironed out.

Funny you should mention the vent, no one else has until I was talking to a freind after the Sunday fly (ing attempt). I am going to check that the vent is off the roof of the tank. I'm pretty sure it is, but I'll check.

FYI.

We had a crew of three working on the engine.
First, the engine speed dropped when I pulled the glow ignitor off, so I changed the plug to a #8 (which I was going to do anyways). The drop went away.
We changed the 11x7 3-blade to a 12x6 2-blade. The 12x6 is exactly what is recommended by the manf.
Engine run like crap. Rough transition, rough everything, flaming out, tons of fuel blowing out, and hydraulic locked 20 times because the carb flooded..

I bent the stops out on the LS needle. We closed both needles, opened the HS up 2.5 turns and just cracked the LS..... I didn't think it would start bc the LS needle was open just 1/16 turn off of closed. Whad'ya know. She run pretty good. Transition was MUCH better, it actually had something that resembled a top speed, idle was the same.[sm=idea.gif]

I don't know what to say about the LS needle. It doesn't make sense. Anyways, there has been a huge improvement in the performance. I didn't get to flight test it because Murphy showed up and caused a bunch of problems...... The day wasn't a total loss, I was bummed bc I couldn't fly though.[sm=cry_smile.gif]

I am going to note all the advice and test each one guys. I'm still planning to use an A3 and an F plug to see if hotter will clean up the exhaust some.
