Yeah thank you for the reply yes I'm using large fuel tubing and I also have a pressure line on my collect ring exhaust, I can say it starts good runs fine just doesn't turn the RPM like it used to I thought maybe rusted Rings or something but it shows and appears to have good compression using my compression gauge guys in the club suggest I use it for a wall mount just kind of disappointing when it used to fly my other Corsair just fine and the old one weighed 6 pounds more
