Thanks Tyler ! I can't take credit for much of what I know (or as someone once said "what I think I know") about Lazairs. Much of what I share was learned from other people and not ideas or notions of my creation. It's hard for me to convey how difficult it was for Lazair guys in the past who had to "learn as they went along" or "make it up as they go" using trial and error. Today people are really lucky as they have a wealth of information at their fingertips they can consider and utilize at will. Very lucky indeed !
As for the fuel system on our planes I say keep it as uncomplicated as possible. The way that Ultraflight had the fuel systems set up for 185s proved to be very good. Continuous lines from tank (in-tank filters) to the carbs has proven to work well also. Multiple splices in the lines, in-line filters, primer bulbs, T's, shut-off's ect. all serve to increase the chance for problems. I say be very wary of your fuel system (no matter how it's set up) as often problems with 2-strokes are fuel related. As Tyler mentions always use quality lines and replace them at reasonable intervals. I also can't stress enough the importance of using fresh gas and oil mix. Never let mixed gas sit up in your tank for any long period.
