I have plenty of lead way on the cowl.
If you can moving the tank closer to the CG will help.Nylon screws for the wing hold down are fine.The O rings in those valves wear out very quickly then it will suck air, cause your engine to go lean. Not a matter of if it's a matter of when.Secure the mount to the firewall with 6-32 screws and blind nuts. Drill the mount and tap 6-32 to secure engine to mount. Tap only about 2/3 through the mount and use a 6-32 screw long enough to just protrude out the back side. This will keep the screw from backing out.Moving the engine back 1/4" will help but 1/2" would be better. I think there is a slightly smaller/lighter muffler available for the engine. if noise is not an issue being a pumped engine the muffler is not required. I realize this is a lot of work but getting the CG right will turn a pig into a good flying airplane. Well worth the effort.
