Have you got a fuel pressure gauge?

I removed the drip trays to better check for leaks and, sure enough, there was blue staining and evidence of leakage around both carb bowls. I have a carb re-build kit on order from Lockwood, supposed to arrive on the 23rd. I am in the process of removing the carbs for the pending rebuild. This is not a trivial operation. Europapa, I had a fuel pressure gage installed and it showed good, constant fuel pressure. I have replaced the fuel pressure gage with the UMA Differential Pressure gage which compares airbox pressure with fuel pressure and provided a reading of the difference. For those who are interested, I will do my best to photo-document the carb removal, rebuild and replacement procedure in my Rotax Owners site. I hope to start posting pictures in a new album tomorrow. http://www.europaowners.org/main.php Blue skies & tailwinds, Bob Borger Europa XS Tri, Rotax 914, Airmaster C/S Prop.
