im installing a 120 4 stroke non pumped in a hanger 9 corsair / i see the centre of the tank is about 2 inches above the needle/ will this cause any performance problems. i had this in a 120 ultra stick and it worked great but the engine was mounted at 90 degree. in the corsair it is on a 45 dgree up from the bottom.

It would certainly be better if it was centered

Try running it and see how it does. I've seen people get away with using a high tank

You will have to watch about it siphoning fuel out on the ground

thankyou w8ye i heard about the siphoning problem we will give it a try .

With all due respect I dont need anyone to fix it I need to find 2 heads for this engine fs 120 with double tappet covers

Clarence Lee is perfectly capable of repairing both heads if you decide to go that way.

Here is a picture of a broken Saito exhaust he repaired

You need the tappet covers or the head?
