  1. Just a thought. get a 5 gallon jug, and drain some gas through the gascolator with the master switch on. Check the fuel flow readings. I see normal readings of 18-20 GPH for both feeding, and slightly less with one clamped off. Clamp the fuel line on each side one at a time and check the readings. Drain at least a couple gallons through. Then try a take off again.
  2. I am not saying to ignore it, but if you have confirmed that there are no fuel leaks, and all other indications (fuel pressure, manifold pressure, RPM) are normal I would fly it. I have made quite a few post maintenance flights on CT's, and have never aborted a take off just because of high fuel flow, and I have seen them before. I would have if there was some other indication that something was wrong. The issue has always went away after a short period of time, and didn't resurface until the next maintenance.
  3. K factor would come more into play if the fuel flow was reading 6 GPH, and actual gallons divided by hours showed that it was only burning 5.5 GPH. The only way to get those real high readings is for the little impeller to spin real fast. This could be from vapor or it could be from an actual fuel leak. My bet is vapor, especially after maintenance if the fuel filter was cleaned, the wings removed, or better yet a hose change. The times I have seen it it was always vapor, and the problem went away in a short time.
  4. That's fuel pressure. Fuel flow would be Flow Scan, or Red Cube with three wires and bullet connectors.
  5. The fuel flow uses bullet connectors, I don't think squeezing them is the way to go.
  6. I have seen this after maintenance before, and it normally rectified itself without having to do anything, My guess is that there are some air bubbles in the system.
  7. It might, but I have never tried it. I did use some braided fishing line once.
  8. There is silicone sealer completely under the light. I have used a utility knife blade, and a thin putty knife before. I have also used some twisted Kevlar thread pulled back and forth like a saw to cut through the silicone before. Just be slow and patient so you don't do any damage.
  9. Like other have said I would request having the wording changed to a new weight and balance must be calculated. I have requested changes in wording before. The worst that can happen is they say no.
  10. I have the luxury of having a set of three scales. If you know anyone who is serious about racing they might have a set you can borrow. I think it would be difficult to get an accurate weight weighing all three point independently. Fuel drained will probably give the most accurate weight, but I would probably base my decision on ow much fuel is onboard now, and whether you have the storage for that much fuel. Myself I have plenty of jugs to drain one that is completely full. I would weigh it with the fairings installed, and AOI onboard. I would remove any extras that you normally carry. The main gear will definitely weigh more than the nose.
  11. Corey, the crossover tube is only on the LS. The CTSW does not have it, it has the vented caps.
  12. For the 7.5mm hose this will work, https://www.ebay.com/itm/192199220787 .
  13. Did you replace the float needle at the rubber replacement? While not on the Rotax rubber replacement list I was told by Lockwood that they will start having issues after 6 or 7 years. Now I had a leaking float valve once, and it did the same thing with fuel running out the airbox. This was right after a carb service with replacement of the float needle, and I couldn't do anything to stop it. I sent the carb to LEAF, and they did something to the valve seat. They said it was a secret fix. I suspect it involved machining of the valve seat.
