I'm curious about your fuel tank.

Thom as far as the dimensions of the tank I would guess about 13 x 16, It's 8 gal. Let me know if you need exact dimensions I'll measure it.

This is due to the fact that the Bing 54 carburetor is over sized for the engine. Also note that this carb, like MANY others, has no linear relationship between throttle-slide movement and cross-sectional area of the throttle bore opened. Butterfly carbs have a similar problem. I thought there was an 'official' definition of 75% power. I don't recall for sure but it seemed like it was something like 100% rpm, then back off 10% rpm. -------- GeoB "Members of Congress should be compelled to wear uniforms like NASCAR drivers, so we could identify their corporate sponsors" Read this topic online here: http://forums.matronics.com/viewtopic.php?p=288641#288641 ________________________________ Message 7 _____________________________________ Time: 01:03:38 PM PST US From: "Jack B.

I checked with http://www.rotaxservice.com/rotax_engines and using the numbers proved from the various engine model spec sheets this is what I found. engine max hp max hp .75 max .75 max |John's hp % max model (cont') rpm hp rpm | rpm (dev') hp 582 65 6,500 49 5,300 |5,800 61 94 447 40 6,500 30 5,200 |5,800 37 93 912ul 79 5,500 59 4,000 |5,000 74 94 912uls 95 5,500 71 4,200 |5,000 89 94 Approximately 75%?

Jack B. Hart FF004 OK john hauck mkIII Titus, Alabama ________________________________ Message 9 _____________________________________ Time: 02:53:33 PM PST US Subject: Kolb-List: 75% Power From: Richard Girard By definition it is when or at what conditions the engine is producing 75% of its rated power. You calculate what that would be, on my 582 it's about 48 HP and according to the graph in the Rotax operations manual for the two strokes on page 10-3 that occurs at about 5200 RPM.

Seems a bit high...I am guessing that the 912uls burns about 5.5 gals hour at 75 % power?
