I have been test flying a Rans S-7 with Jabiru 3300 6 cylinder for 11 hours or so. The owner replaced the standard Bing carb (good move) with a Rotec as the Bing was running way lean and without a needle swap we couldnt use so thought why not try a Rotec instead.
It has performed really well straight out of the box, starts well, runs smoothly, easy to lean. Only drawbacks I have incountered are that it siphons fuel unless you turn the fuel tap off (high wing configuration) and coughs if you are a bit quick with the throttle (no accelerator pump).

Other than that its really nice, and since then I have decided to fit one to my Pitts.

Default very interested in TBI installations

Joe, Michel

I will be very interested to see some pictures of Rotec TBI installations on Lycomings. If everything works out, we will be hanging the engine today for a first trial. We will be soon trying to get our Rotec TBI installation done. I'm interested if you are attaching the regulator directly to the housing or have it attached only by the fuel lines?

Michel,

(note my above post)

I have one cylinder (#1) running a bit lean (high EGT's). In trying to pinpoint the problem, I believe it could be the TBI. By pulling the black knob back slightly, the EGT's stabilize. I'm figuring the slide slightly protruding is creating turbulence and thus mixing the fuel/air mixture better. Are you by any chance having anything similar?

I'll see what I can do to insert some installation photo's

Bob
