Hello group, I’m an A&P who is fairly new to working on Rotax ( I passed line and maintenance courses last fall) and my current gremlin is a Tecnam P2002 Sierra, flying a 912ULS. Customer just got his carbs redone with motive aero. After carburetor install with new crush washers on the fuel feed lines, we balanced the carbs nicely, but the problem is that the engine won’t make full static.
The carburetors are both at full open stop and the throttle cables are slacked, but engine speed never advances past 4800, stabilizing around 4750-4780. Previous engine runs before pulling the carbs yielded no issues, everything in the right ranges.
I called Motive and they said to do a compression check and inspect a few things, but in my mind either I’m doing everything wrong here or there’s something up with these overhauled carburetors.
I need someone smarter than myself here. Thank you.
