Thanks for the fast reply...makes perfect sense. I'll open the wings again and add another line from the front of the tanks, I can "tee" them right at the back of the tanks, I think....but it's worth the effort.
hello bill, i have a 801 completed in dec. im running a 0-360 as well and i share your pain with the peice of shit cowling. i made a mold and pulled one out of fiberglass and have put 60 plus hours now with clylinder head temps never over 350. also made it to fit a vans air box as i made the mistake of buying the air box from zenith. hell, the filter was for 100 hp cont. you might as well go with a 10 row oil cooler as oil temps are an issue unless it never gets over 80 deg where your at. anyway, everything working well now so i am in process of making one out of carbon fiber to shed weight as these planes are a bit nose heavy. i got 27 lbs in rear of fuse to improve handling in short field stuff
Bill, It seems you have a common problem with the cowling for the 801/640. I am finishing my 640, which is the same cowling and FWF as the 801, and I also had to open my blisters about and inch. I have also noticed that other 640 builders have had to do the same. I cut a 3 sided "flap" in my cowling to open it up. Then did quite a bit of glass work followed by some carbon fiber and kevlar on the inside for strength. I have some pictures I can send you if you are interested. Email at email@example.com.
